Officecli XLSX

OfficeCLI XLSX Skill

运行环境与交付链（本系统专用，先读这一段）

officecli 已经预装在沙盒镜像的 /usr/local/bin/officecli，不要联网安装、不要 curl。 bash 工具直接调用即可，自检用 officecli --version。

所有命令都在沙盒里执行，文件一律落在 /workspace/ 下。一次完整作业 = 3 步 + 1 步交付：

# Step 1（仅当用户上传过原始文件）把 artifact 送进沙盒
sandbox_put_artifact(artifact_id="<用户文件的 file_id>", dest_path="/workspace/in.docx")

# Step 2 用 bash 跑 officecli —— 本文件下面讲的全部命令都在这一步里
bash("officecli create /workspace/out.docx")

# Step 3 把成稿从沙盒取出、登记成 artifact，拿到新的 file_id
sandbox_get_artifact(src_path="/workspace/out.docx", name="终稿.docx")

# Step 4（必做）交付给用户
pin_to_workspace(file_ids=["<新 file_id>"])

铁律：

• sandbox_put_artifact = 放进沙盒，sandbox_get_artifact = 从沙盒取出，别搞反；两个路径参数都必须以 /workspace/ 开头。
• 拿到 file_id 却不 pin_to_workspace 就等于没交付，用户看不到文件。多个产物一次性放进同一个列表，别分多次调用。
• 下文示例里的 $FILE 和相对路径，都要换成 /workspace/ 下的绝对路径。
• 下文的可视化质检（view <file> screenshot / view <file> html）依赖沙盒内的 Chromium，镜像已预装；截图失败就按下文 fallback 走 view html，并如实标注「未做视觉验证」，不要谎报 PASS。
• 导出 PDF 不要用 officecli view <file> pdf —— 那个模式依赖本系统没有安装的 exporter 插件，必然失败。改用沙盒里的 LibreOffice： soffice --headless --convert-to pdf --outdir /workspace /workspace/out.docx。.xlsx / .pptx 换掉扩展名同理，但要沙盒里装了 LibreOffice Calc / Impress 才转得动；转换报错就如实告诉用户 PDF 没导出成功、主产物仍是原文件，不要谎报已导出。

⚠️ Help-First Rule

This skill teaches what good xlsx looks like, not every command flag. When a property name, enum value, or alias is uncertain, consult help BEFORE guessing.

officecli help xlsx                         # List all xlsx elements
officecli help xlsx <element>               # Full element schema (e.g. pivottable, chart, cf)
officecli help xlsx <verb> <element>        # Verb-scoped (e.g. add chart, set cell)
officecli help xlsx <element> --json        # Machine-readable schema

Help reflects the installed CLI version. When this skill and help disagree, help is authoritative.

Shell & Execution Discipline

Shell quoting (zsh / bash). Excel paths contain [], and number formats contain $. Both are shell metacharacters. Rules:

• ALWAYS quote element paths: "/Sheet1/row[1]", not /Sheet1/row[1].
• Use single quotes for any prop value containing $: numFmt='$#,##0'.
• For formulas with cross-sheet ! references, use batch with a <<'EOF' heredoc (see Known Issues).
• \n and \t in a prop value ARE interpreted by the CLI — \n is a real in-cell line break (pair with --prop wrapText=true), \t a tab — consistent across xlsx / docx / pptx. Double them (\\n) for a literal backslash-n (rarely wanted). ($ is the shell layer above — single-quote it.)

Incremental execution. Run commands one at a time and read each exit code. officecli mutates the file on every call; a 50-command script that fails at command 3 will cascade silently. One command → check output → continue.

Requirements for Outputs

Before reaching for a command, know what a good xlsx looks like. These are the deliverable standards every workbook MUST meet.

All Excel files

Zero formula errors. Every delivered workbook MUST have ZERO #REF!, #DIV/0!, #VALUE!, #NAME?, #N/A. No exceptions — guard denominators with IFERROR or IF(x=0,...).

Formulas, not hardcoded values. If a number can be computed from other cells, it is a formula. Hardcoding 5000 where =SUM(B2:B9) belongs breaks the contract that the workbook stays live when inputs change. This is the single most important rule in this skill.

Professional font. Use one consistent, professional font across the workbook (Arial / Calibri / Times New Roman). Don't mix four fonts because one sheet came from CSV.

Explicit widths. There is no auto-fit. Any column the user will read MUST have width set — default 8.43 chars clips everything. Sensible starts: labels 20-25, numbers 12-15, dates 12, short codes 8-10.

Preserve existing templates. When editing a file that already has a look, match it. Existing conventions override these guidelines.

Visual delivery floor (applies to EVERY workbook)

Before you declare done, run officecli view "$FILE" html and Read the returned HTML path to confirm all of these:

• No ### in any cell. ### means a column is too narrow for its widest value. Every column the user reads needs an explicit width. ### in a delivered file is unfinished work, never "a small visual nit".
• No truncated titles. Sheet titles, section headers, long labels must fit. Widen the column or apply wrapText=true on the cell.
• No placeholder tokens rendered as data. $fy$24, {var}, <TODO>, xxxx must never appear in a cell, chart title, series name, or legend. These are build-time tokens that escaped replacement.
• Pie / doughnut slices have distinct fill colors. If the slices render same-colored, switch to bar / column or set colors=... explicitly.
• No empty trailing pages / empty chart anchors. anchor=D2:J18 over empty source cells looks like a broken chart.

If any of the above fails, STOP and fix before declaring done.

Print layout. Any sheet the user may print or send as a board pack needs page setup. Default portrait + no fit-to-page splits wide tables and charts mid-way. Pick the fit mode by sheet shape:

# Summary / chart / dashboard sheet (small, ≤ ~40 rows): fit to a single page.
officecli set "$FILE" "/Summary" --prop orientation=landscape --prop fitToPage=true
# Tall data table (dozens+ rows): fit WIDTH only, let height paginate naturally.
# fitToPage=true here crushes every row onto one page → unreadable (### dates, 5px rows).
officecli set "$FILE" "/Data" --prop orientation=landscape --prop fitToPage=1x0

fitToPage=true == 1x1 == fit both axes to one page — correct only when the sheet is already short. 1x0 = fit 1 page wide, unlimited pages tall. Trigger: sheet holds a chart, or > 8 columns, or the user's ask mentions print / board / investor.

Financial models only — skip this section if you are building a template, tracker, CSV import, or operational sheet

Scope: budgets, forecasts, 3-statement models, valuation, any $-heavy analytical workbook. A customer-support tracker or onboarding template does not need this section.

Color coding — industry standard. Five core colors used as a language, not decoration. A reviewer should tell what a cell IS by color alone — before reading the formula.

A reviewer should tell what a cell IS just by its color — before reading the formula. This is a communication contract, not a cosmetic preference.

Number formatting — standards, not preferences.

• Years are text, not numbers. Format 2026 not 2,026 — use numFmt="@" or set type=string.
• Currency carries its unit in the header (Revenue ($mm)), not in every cell.
• Zeros display as -, not 0. Use $#,##0;($#,##0);"-".
• Percentages default to one decimal: 0.0%.
• Negatives use parentheses: (1,234) not -1,234.
• Valuation multiples use 0.0x format (EV/EBITDA, P/E, etc.).

Assumptions live in cells, not inside formulas. =B5*(1+$B$6) is correct; =B5*1.05 is a bug. Document each blue hardcoded input with an adjacent source note in the next cell or a cell comment:

Source: Company 10-K, FY2024, Page 45, Revenue Note
Source: Bloomberg, 2026-05-02, AAPL US Equity
Source: Management guidance, Q2 2026 earnings call

Any hardcoded number without a source is an undocumented assumption — a reviewer cannot audit it.

Common Workflow

Six steps. Every non-trivial build follows this shape.

1. Open/save lifecycle. Use officecli open <file> at the start and officecli save <file> at the end to flush to disk — save only writes and leaves the resident warm for follow-up edits; reach for officecli close <file> only to release the resident on a one-shot handoff. Both are always safe (never error or lose work). For many cells, use batch: ≤ 50 ops/block recommended; tested up to 80+ ops per block on pure value-set payloads with zero failures. Cross-sheet formula batches are the exception — run those non-resident, single heredoc (see Known Issues). Flush only at the non-officecli boundary: officecli's own reads always see your edits; run save/close only before a non-officecli program reads the file (openpyxl/pandas, Excel, a renderer, delivery).
2. Create or load. officecli create "$FILE" (new) or officecli view "$FILE" outline (existing — get the lay of the land first).
3. Build incrementally. One command, read the output, continue. After any structural op (new sheet, chart, named range, pivot), run get on it to confirm shape before stacking more on top.
4. Format. Column widths, number formats, freeze panes, tab colors, header fills. Formatting is not optional polish — per "Requirements for Outputs" it is part of the deliverable.
5. Save, then reckon with the cache. officecli save <file> writes to disk. Newly-added formulas ship without cached values; when a human opens the file in a spreadsheet app, the app recalculates and populates them. But your downstream INDEX/MATCH, SUMPRODUCT, or any formula that references an upstream formula will cache whatever the upstream cached at write-time — often 0 or a stale value — and that cached lie survives into non-recalculating readers. After any multi-formula build involving array formulas (SUMPRODUCT, SUMIFS with dynamic criteria) or cross-sheet chains, re-touch every downstream cell (run set again with the same formula) so the engine recomputes its cache from the freshly-cached upstream. ⚠️ Re-touch on cross-sheet chains via resident is unreliable (see Batch / resident caveats) — prefer non-resident set for the re-touch pass. Then officecli get a few downstream cells and eyeball that their cachedValue= is plausible. validate is safe with a resident open and itself flushes pending edits to disk (same as docx / pptx).
6. QA — assume there are problems. See the QA section. You are not done when your last command exited 0; you are done after one fix-and-verify cycle finds zero new issues.

Quick Start

Minimal viable xlsx: 3 months of revenue + a total formula + column widths + a currency format. Adapt, don't copy-paste — your file, your data.

officecli create "$FILE"
officecli open "$FILE"
officecli set "$FILE" /Sheet1/A1 --prop value=Month --prop bold=true
officecli set "$FILE" /Sheet1/B1 --prop value=Revenue --prop bold=true
officecli set "$FILE" /Sheet1/A2 --prop value=Jan
officecli set "$FILE" /Sheet1/A3 --prop value=Feb
officecli set "$FILE" /Sheet1/A4 --prop value=Mar
officecli set "$FILE" /Sheet1/B2 --prop value=42000 --prop numFmt='$#,##0'
officecli set "$FILE" /Sheet1/B3 --prop value=45000 --prop numFmt='$#,##0'
officecli set "$FILE" /Sheet1/B4 --prop value=48000 --prop numFmt='$#,##0'
officecli set "$FILE" /Sheet1/A5 --prop value=Total --prop bold=true
officecli set "$FILE" /Sheet1/B5 --prop formula="SUM(B2:B4)" --prop bold=true --prop numFmt='$#,##0'
officecli set "$FILE" "/Sheet1/col[A]" --prop width=12
officecli set "$FILE" "/Sheet1/col[B]" --prop width=15
officecli close "$FILE"
officecli validate "$FILE"

Verified: validate returns no errors found, B5 resolves to 135000. This is the shape of every build: open → set cells/formulas → format → close → validate.

CSV / bulk import

Native import command (preferred for CSV/TSV). Fastest path; loads a CSV into a sheet in one call. --header sets AutoFilter + freeze pane on row 1. Widths and numFmt still need a follow-up pass (per D-12 in Dashboard skill).

officecli import "$FILE" /Sheet1 --file data.csv --header
officecli import "$FILE" /Sheet1 --file data.tsv --format tsv --header
officecli import "$FILE" /Sheet1 --stdin --start-cell B2 < data.csv

Python + batch fallback — use when you need custom type coercion, formula injection, or the CSV lives inside another data pipeline. Recipe for 600-6000+ cells:

# gen_batch.py — produces batch chunks of 80 value-set ops each
import csv, json
ops = []
with open("data.csv") as f:
    reader = csv.reader(f)
    for r, row in enumerate(reader, start=1):
        for c, val in enumerate(row):
            col = chr(ord('A') + c)
            ops.append({"command":"set","path":f"/Data/{col}{r}",
                        "props":{"value": val}})
for i in range(0, len(ops), 80):
    print(json.dumps(ops[i:i+80]))

python gen_batch.py | while IFS= read -r chunk; do
  printf '%s\n' "$chunk" | officecli batch "$FILE"
done

Outcome: 648-row retail CSV (6490 cells) loads in ~30s, zero failures. Tune: start at 80 ops/chunk, drop to 40 if any chunk fails. Numeric type inference and formulas come later via targeted set — batch in this recipe is pure value injection.

Reading & Analysis

Start wide, then narrow. outline first tells you what sheets exist and where the data is; jump into view / get / query only once you know where to look.

Open the rendered workbook to eyeball your own work.

• officecli view $FILE html — Read the returned HTML to audit the rendered output. Each sheet is addressable, charts render inline. Catches ###, placeholder leakage, pivot layout, row-height clipping.
• officecli watch $FILE keeps a live preview running for the human user — they open it at their own discretion. Use when the user wants to watch along; agent self-check uses view html above. Use view html as your first visual check after a batch of edits — fix at source. For final visual verification, the user opens the .xlsx in their Excel / WPS / Numbers viewer.

Orient. Sheets, dimensions, formula counts.

officecli view "$FILE" outline

Extract. Plain text dump for content QA or LLM context; scope with --start / --end / --cols for big files.

officecli view "$FILE" text --start 1 --end 50 --cols A,B,C

Other view modes worth knowing: annotated (cell values + types/formulas + warnings), stats (numeric summaries), issues (broken formulas, empty sheets, missing refs).

Round-trip dump. officecli dump "$FILE" [path] serializes the workbook — or one worksheet (/Sheet1, /sheet[N]) — into a replayable batch JSON; officecli batch new.xlsx --input dump.json replays it. Use it to learn from an existing workbook's structure or clone/adapt a template instead of reading raw OOXML. Coverage per dump --help; subtree dumps don't carry workbook-level resources (settings, named ranges) — the replay target must already define them.

officecli dump "$FILE" -o blueprint.json            # whole workbook
officecli dump "$FILE" /Sheet1 -o sheet.json        # one worksheet
officecli batch new.xlsx --input blueprint.json

Inspect one element. Use XPath-style paths. Always quote — shells glob [N].

officecli get "$FILE" "/Sheet1/A1"            # one cell
officecli get "$FILE" "/Sheet1/A1:D10"        # range
officecli get "$FILE" "/Sheet1/chart[1]"      # chart
officecli get "$FILE" "/Sheet1/table[1]"      # ListObject
officecli get "$FILE" "/namedrange[1]"        # workbook-level named range

Add --depth N to expand children; add --json for machine output. Full element list: officecli help xlsx.

Query across the workbook. CSS-like selectors. Use for systematic checks (formula coverage, error cells, empty headers) rather than hand-walking.

officecli query "$FILE" 'cell:has(formula)'       # every formula cell
officecli query "$FILE" 'cell:contains("#REF!")'  # broken references
officecli query "$FILE" 'cell[type=Number]'       # typed filter
officecli query "$FILE" 'Sheet1!B[value!=0]'      # sheet-scoped

Operators: =, !=, ~= (contains), >=, <=, [attr] (exists).

Merge cells shortcut. officecli query $FILE merge or mergedrange — both are aliases for mergeCell. Returns every merged range in the workbook without hand-walking <mergeCell> entries.

When the data is big enough that a row-walk is useless, reach for Excel's own analytical elements:

• Build a pivot table with officecli add (--type pivottable) to group/aggregate without writing 20 SUMIFs. Attach a slicer (--type slicer) to give the reader a filter UI.
• Drop a sparkline (--type sparkline) in a row to show per-row trends — cheaper than one line chart per row and they print inline. type is a strict enum: line | column | stacked (plus aliases winloss / win-loss → stacked). Invalid type= values hard-fail — no silent fallback to line anymore.
• Run officecli help xlsx pivottable, officecli help xlsx slicer, officecli help xlsx sparkline for the exact prop names.

Creating & Editing

Ninety percent of a build is cells, formulas, formatting, and one or two charts. The verbs: add (new element), set (change a prop), remove, move, swap, batch.

Cells and formulas

Set a value and its format in one call. Never write = at the start of a formula — the CLI strips it.

officecli set "$FILE" /Sheet1/B5 --prop formula="SUM(B2:B4)" --prop numFmt='$#,##0'
officecli set "$FILE" /Sheet1/C5 --prop formula="B5/A5" --prop numFmt="0.0%"

Structural properties (width, height, freeze, tabColor) live on row / col / sheet nodes:

officecli set "$FILE" "/Sheet1/col[A]" --prop width=20
officecli set "$FILE" "/Sheet1/row[1]" --prop height=22
officecli set "$FILE" "/Sheet1" --prop freeze=A2 --prop tabColor=1F4E79

Named ranges

Prefer named ranges over $B$6 in formulas. They self-document (GrowthRate beats $B$6) and they let you move the assumption cell without breaking formulas. Because ref values contain both ! and $, add them through a batch heredoc:

cat <<'EOF' | officecli batch "$FILE"
[
  {"command":"add","parent":"/","type":"namedrange","props":{"name":"GrowthRate","ref":"Sheet1!$B$6"}}
]
EOF

See officecli help xlsx namedrange for the full schema.

Batch JSON does NOT accept shell aliases. Inside batch props, always use the full dotted name — "font.color": "FF0000", "font.size": 14, never "color": "FF0000" (ambiguous: text vs fill). On a bare cell, even the shell form is rejected: --prop color=1F4E79 errors with ambiguous in cell context — use 'font.color' (text) or 'fill' (bg). Rule: in any batch JSON or cell prop, write font.color / fill explicitly. parent should be "/" for workbook-level elements and "/SheetName" for sheet-scoped; empty string is not equivalent.

Charts

Chart types live under officecli help xlsx chart — the enum is long (20+). Pick the right one for the message: column for category comparison, line for time series, pie only when slices are self-evidently proportional, scatter for correlation. Avoid exotic types unless they answer a specific question.

Three ways to feed chart data. Pick one per chart — mixing them at add-time is a common trap.

The single-column trap. dataRange="Sheet1!B2:B13" looks like "value column" but the engine rejects it with Chart requires data. Either widen the range to include the category column (A2:B13), or switch to form (c) with explicit series1.categories.

Move / resize a chart after create: set chart[N] --prop anchor="F5:N25" (also --prop x= --prop y= --prop width= --prop height=). Series are still immutable — to add/change a series, officecli remove the chart and officecli add with the full series list. Note remove chart[1] shifts chart[2] → chart[1] and re-add appends at the end — to preserve chart order, remove all and rebuild in order.

Anchor sizing. No auto-fit. A column chart with 5-6 categories + 2 series needs roughly A5:L22 (12 cols × 18 rows) to show all labels uncut. Narrower and X-axis labels clip; wider and the chart can split across pages on print/export. If in doubt, start narrow, preview via view html (Read the returned HTML path), widen in increments. Page layout (below) is the other half of the fix.

Chart dataRange — always prefix with the sheet. Even when the chart lives on the same sheet, write dataRange="Summary!A17:C22", not A17:C22. The sheet-less form works inconsistently; the prefixed form is 100% reliable.

officecli adds extended chart types the classic Excel object model lacks: boxWhisker, waterfall, funnel, histogram, treemap, sunburst, pareto. Use them when the data calls for them.

NEVER put unreplaced template tokens in chart title / series name / legend / axis title. $fy$24, {var}, <TODO>, $VAR, {{placeholder}} render literally in the legend — validate passes, but a CFO sees $fy$24 where "FY2024" should be. Always bind to final text or a cell reference (title="FY2024 Revenue" or series1.name="Sheet1!A1").

Conditional formatting

Three common flavors, each with its own prop shape (consult officecli help xlsx cf):

• Color scales: cells shaded on a gradient by value — type=colorscale with minColor / midColor / maxColor.
• Data bars: in-cell bars showing magnitude — type=databar. Set explicit min / max for consistent scaling across a column; defaults are valid if you omit them.
• Formula rules (the formulacf element): highlight row when a condition is true — type=formula with formula="$C2>1000" and a fill/font.

Rule: apply CF sparingly. A workbook where every cell is colored tells the reader nothing.

Data validation

Input cells in trackers and templates MUST carry data validation. It's cheap and it stops entire classes of downstream bugs. Three list-source patterns — pick based on where the allowed values live.

(a) Inline list — allowed values are short and fixed in the rule itself.

officecli add "$FILE" /Sheet1 --type validation \
  --prop sqref="C2:C100" --prop type=list \
  --prop formula1="Yes,No,Maybe" \
  --prop showError=true --prop errorTitle="Invalid" --prop error="Select from list"

(b) Named range (preferred for cross-sheet lookups) — allowed values live in another sheet and may grow. Define the named range first, then reference it. Use a batch heredoc because ref contains ! and $:

cat <<'EOF' | officecli batch "$FILE"
[
  {"command":"add","parent":"/","type":"namedrange","props":{"name":"StatusList","ref":"Lookups!$A$2:$A$4"}},
  {"command":"add","parent":"/Sheet1","type":"validation","props":{"sqref":"B2:B100","type":"list","formula1":"=StatusList"}}
]
EOF

(c) Direct cross-sheet range — no named range, raw Lookups!$A$2:$A$4 inside formula1. Also needs a batch heredoc to keep ! and $ intact:

cat <<'EOF' | officecli batch "$FILE"
[
  {"command":"add","parent":"/Sheet1","type":"validation","props":{"sqref":"C2:C100","type":"list","formula1":"Lookups!$A$2:$A$4"}}
]
EOF

If you write the cross-sheet variant as --prop formula1=... on the shell, the ! gets shell-mangled into \! and the dropdown will silently fall back to no list. Verify with officecli get "$FILE" /Sheet1/validation[N] — formula1= must show a plain !, no backslash.

Other common type values: decimal, whole, date, textLength, custom. See officecli help xlsx validation for operators and the full prop list.

Other elements (one-liners)

• Tables (ListObjects) — add --type table with a range; gives auto-filter + structured refs. officecli help xlsx table.
• Comments — add --type comment; use for documenting hardcoded assumptions. officecli help xlsx comment.
• Sheet reordering — officecli move, not swap. swap only works on row/cell paths.

Chart Axis-by-Role

Editing a chart axis in place is cheaper than rebuilding the chart. Address axes by role (value = Y, category = X), not by index — the XML order isn't stable.

officecli get "$FILE" "/Sheet1/chart[1]/axis[@role=value]"
officecli set "$FILE" "/Sheet1/chart[1]/axis[@role=value]" --prop min=0 --prop max=100000
officecli set "$FILE" "/Sheet1/chart[1]/axis[@role=category]" --prop title="Month"

Safe props: title, min, max, majorGridlines, visible, labelRotation.

QA (Required)

Assume there are problems. Your job is to find them.

Your first workbook is almost never correct. Treat QA as a bug hunt, not a confirmation step. If you found zero issues on first inspection, you were not looking hard enough. The formulas look fine until you check two of them against source cells.

Minimum cycle before "done"

1. officecli view "$FILE" issues — empty sheets, broken formulas, missing refs.
2. officecli view "$FILE" annotated (sample ranges) — values + types + warnings.
3. For every Excel error type, query it:

   officecli query "$FILE" 'cell:contains("#REF!")'
   officecli query "$FILE" 'cell:contains("#DIV/0!")'
   officecli query "$FILE" 'cell:contains("#VALUE!")'
   officecli query "$FILE" 'cell:contains("#NAME?")'
   officecli query "$FILE" 'cell:contains("#N/A")'
   

4. officecli validate "$FILE" — safe with a resident open; validate flushes pending edits to disk itself.
5. Visual pass — walk every sheet via the HTML preview. Run officecli view "$FILE" html and Read the returned HTML path. Each sheet renders with charts inline. Scan for ###, truncated titles, placeholder tokens ($fy$24, {var}, <TODO>), sliced charts, white-slice pie charts, empty chart anchors — STOP and fix before declaring done. "validate pass" is not delivery; "the preview looks like a real workbook" is delivery. For human preview, run officecli watch "$FILE" (user opens the live preview at their own discretion) or have them open the .xlsx directly in Excel / WPS / Numbers.
6. Print layout fix (wide tables / multi-chart sheets). When a sheet holds a chart or a wide table and the user will print it, set per-sheet page layout — but match the fit mode to the sheet's height:

   # Short summary / chart sheet → fit to one page.
   officecli set "$FILE" "/Summary" --prop orientation=landscape --prop fitToPage=true
   # Tall data table → fit width only (fitToPage=true would crush all rows onto one unreadable page).
   officecli set "$FILE" "/Data" --prop orientation=landscape --prop fitToPage=1x0
   

   Outcome: charts/wide tables print without mid-chart splits; tall tables stay readable across natural page breaks. Apply to every sheet that holds a chart or a > 8-column table.
7. If anything failed, fix, then rerun the full cycle. One fix commonly creates another problem.

officecli view issues + view html are the structural QA pair: issues catches broken formulas and empty sheets; view html (Read the returned HTML path) catches ###, truncation, and token leakage. Chart fill colors / theme tints can vary across viewers — spot-check in the user's target viewer when color fidelity matters.

Formula verification checklist

• Pick 2-3 formulas at random. Run officecli get on each. Confirm the formula string is what you intended and cachedValue= is what you expect — arithmetic in your head.
• Cached value sanity on every summary cell. Any cell that aggregates (COUNTA / COUNTIF / SUMPRODUCT / INDEX&MATCH) must have a plausible cachedValue. If a progress tracker shows 199 / 199 / 100% on a blank template, the cache is lying — re-touch the formula via set (forces recompute) or manually set a correct cached value. Do NOT ship "validate passes but the numbers are fiction".
• Spot-check one cell per numeric column. % columns showing integer 0.0% throughout means the denominator is wrong or the numerator is cached stale — investigate one cell, fix the pattern.
• Ranges include every row: off-by-one on SUM(B2:B12) when data goes to B13 is the most common bug.
• Cross-sheet formulas (Sheet1!A1) contain no \!. If officecli get shows Sheet1\!A1, the ! was shell-corrupted — delete and re-enter via batch/heredoc.
• Named ranges (officecli get "$FILE" "/namedrange[1]") point at what their names claim.
• Every / denominator is guarded — IFERROR(x/y, 0) or IF(y=0, 0, x/y).
• Chart data vs source cells: for every chart with inline data, spot-check data points against officecli get of the source cells.
• Chart title / series name / legend contain no unreplaced tokens ($...$, {var}, <TODO>). Grep the chart via officecli get /Sheet1/chart[N].

Template QA

When editing a template, check for leftover placeholders — they look like content and slip past validate:

officecli query "$FILE" 'cell:contains("{{")'
officecli query "$FILE" 'cell:contains("xxxx")'
officecli query "$FILE" 'cell:contains("TBD")'

Fresh eyes

When you finish a workbook, open it fresh. Read view text / HTML preview top-to-bottom as if you are a new reviewer — look for formulas, numbers that look off, formatting inconsistency, missing data.

Honest limit

validate catches schema errors, not design errors. A workbook can pass validate with every number wrong. The checklist above — especially spot-checking formulas against source cells — is how you catch what validation can't.

Known Issues & Pitfalls

The cross-sheet ! trap (short)

Shells (bash history expansion, zsh splitting) and CLI arg parsing mangle ! in Sheet1!A1 into \!. A formula containing \! is silently broken — it renders as literal text and references nothing.

Fix. Use a batch heredoc with single-quoted delimiter (<<'EOF'), which disables all shell expansion:

cat <<'EOF' | officecli batch "$FILE"
[{"command":"set","path":"/Summary/B2","props":{"formula":"Revenue!B13"}}]
EOF

Verify. After writing, officecli get the cell; formula= must show a plain ! with no backslash.

CLI bug backlog (short)

CLI constraints and gaps to work around — not defects in the output file.

• Chart series are immutable after create — to add/change a series: remove + add with the full series list. (Position is mutable: set chart[N] --prop anchor= / x/y/width/height.) remove chart[N] shifts subsequent indices down; re-add appends at end.
• Cross-sheet formula batches run fine through a resident — a prior "deadlocks even at 3-5 ops" caution no longer reproduces. Pure value-set batches stay reliable at 50-80+ ops too. If you ever hit a hang, fall back to a non-resident one-big-batch or individual set. Multiple resident processes on the same file/machine can still contend — expect non-deterministic hangs if another agent/session holds a resident on the same file.
• Conditional formatting naming asymmetry — the element name for --type is conditionalformatting; the path suffix is /cf[N]. Use officecli help xlsx conditionalformatting for schema, /cf[N] for paths.
• Sheet position prop on add — help says Add processes position, but the prop is often ignored. Reorder with officecli move --index / --after / --before after creating the sheet.
• remove /sheet[N] cascade guard — rejects sheet remove/rename when the sheet is referenced by validation / conditional format / sparkline / hyperlink / named range on another sheet. Remove those dependent elements first, then remove the sheet.
• Batch JSON rejects cell color alias — inside batch props, "color": "FF0000" errors ambiguous in cell context — use 'font.color' (text) or 'fill' (bg). The CLI at shell level accepts --prop color=... / --prop size=14 as aliases on non-cell elements, but inside batch JSON on a cell always write the full dotted name: "font.color", "font.size", "font.name".

Renderer caveats (cross-viewer color fidelity)

officecli view html is the right tool for structural QA (overflow, truncation, placeholder leakage, layout) — Read the returned HTML path. Some chart rendering details vary across the viewer the end user opens the file in. Observed divergences:

• Pie / doughnut fill colors may collapse to a single theme tint in some viewers (slices look "all white" or "all one color"). The file may be fine in the user's target viewer.
• Line chart / column chart series colors may drift from the workbook theme in some viewers.
• Form-control checkboxes may render as double-boxed in some viewers.

Before calling a color or chart "broken", open the file in the user's actual target viewer. If it looks correct there, the problem is viewer rendering, not data — do not chase it. The CLI's structural checks (###, truncation, placeholder text, layout) remain authoritative.

Escape layers (shell quoting is above; these are the extras)

$ is the shell layer (single-quote it, above). \n / \t in a prop value ARE interpreted by the CLI into a real newline / tab. Two more layers:

• JSON level (batch). Standard JSON escapes — "\n", "\t", "\"". A real backslash in the final string is "\\\\".
• Excel level. \n in a cell is a real line break — pair with --prop wrapText=true so Excel shows the wrap. Works in a shell-quoted prop directly (--prop value='a\nb'); "\n" inside batch JSON gives the same. When in doubt, officecli get the cell and compare character-for-character.
