Univer CLI

univer-cli

univer is a spreadsheet engine in the terminal. Use it when an agent needs real workbook semantics: sheets, ranges, formulas, formatting, layout, previews, imports, exports, or versioned workbook state.

Install the CLI with npm i -g univer-cli. Update the CLI with univer update. The executable is univer; unv may be available as a short alias.

Core Mental Model

Treat workbook-visible state as the source of truth. A successful command summary, package metadata, or an internal manifest does not prove that sheet names, cell values, formulas, formatting, or exported handoff files are correct.

The workbook path is the local identity. Pick one explicit path such as ./budget.univer and use that path as the CLI target. Do not target workbooks by unitId, sessionId, manifest ids, or runtime ids.

.univer and .unv files are CLI operation targets, not agent-editable data stores. Read and write workbook data through public CLI surfaces such as inspect, search, pipe, run, export, status, and commit.

Use univer help and univer help <command...> for exact syntax. For run scripts, use univer help run and univer help run <topic> before relying on unfamiliar APIs.

Use When

Use this skill when the task involves spreadsheet or workbook work, especially:

• creating, importing, exporting, or handing off .xlsx, .csv, .univer, or .unv files
• inspecting workbook shape, sheets, ranges, formulas, formatting, or visible cell state
• locating content-defined rows, columns, headers, or cells before editing
• making bounded edits to cells, formulas, formatting, charts, shapes, floating images, layout, or sheet structure
• streaming rectangular workbook data through shell tools before reading it into context
• writing generated matrix data back into a sheet-qualified range
• previewing workbook state locally with univer view
• reading submitted local viewer review comments with univer view comments
• creating, restoring, resetting, pulling, or syncing local workbook changesets
• proving that a workbook-visible mutation or export is correct enough to hand back

Default Operating Loop

1. Pick one explicit workbook path, for example ./budget.univer.
2. Create or import a workbook first if no .univer or .unv target exists.
3. Inspect workbook-visible state before deciding where to write.
4. Locate targets from visible headers, values, formulas, or inspected ranges.
5. Choose the smallest public CLI surface that fits the task.
6. Mutate through the CLI, not by editing package internals.
7. Verify changed workbook-visible state with inspect, pipe out, or another public read.
8. Export only after verification when the user needs a handoff file.
9. After changes have been verified, if the user may need to inspect, audit, or review the final workbook, check the current agent tool surface first. If a browser tool is available, run univer view "$WB" --no-open --json, open the returned URL with that browser tool, and include the URL in your response. If no browser tool is available, run univer view "$WB" --open --json; --open uses the OS browser opener, and the CLI returns a prepared URL and diagnostic if the browser cannot be opened automatically.
10. Commit or sync only after verified changes when versioning is part of the workflow.

Hard Rules

• Do not read .univer or .unv internals to infer workbook contents.
• Do not write, patch, unzip, rezip, rename internal files, or manipulate workbook package contents.
• Do not inspect manifest.json, snapshots, mutation logs, or package fragments as a substitute for workbook-visible reads.
• Do not guess sheet names, row numbers, formulas, ranges, or changed cells from memory or file metadata.
• Do not treat stdout summaries as proof of workbook state. Verify with a workbook-visible read.
• Do not invent commands or run APIs. Check univer help and documented run topics.

Direct package access can corrupt workbooks or teach the agent false state. If the CLI cannot read what you need, diagnose the CLI/runtime path instead of bypassing it.

Command Selection

Use canonical command help such as univer help inspect range and univer help pipe out. Top-level help group headings are visual sections only; do not run group-prefixed topics such as univer help read inspect range.

Execution Results

Treat non-zero exit as failure even when stdout is partially present. Read stderr before changing approach; it usually contains the stable diagnostic code, usage, and retry examples.

Keep data stdout clean in shell pipelines. If diagnostics are needed, capture stderr separately so downstream tools receive only workbook data.

univer inspect range "$WB" --range 'Sheet1!A1:D20' > ./range.md 2> ./range.err
status=$?
if [ "$status" -ne 0 ]; then
  sed -n '1,80p' ./range.err
  exit "$status"
fi
sed -n '1,40p' ./range.md

Workflow Recipes

These are verified command shapes. Replace paths, sheet names, and ranges with inspected workbook facts.

Create Or Import, Then Inspect

WB=./orders.univer
univer import ./orders.csv "$WB" --json
univer inspect workbook "$WB"
univer inspect range "$WB" --range 'Sheet1!A1:D4'

Use new when the task starts from a blank workbook:

WB=./workbook.univer
univer new "$WB" --name "Workbook"
univer inspect workbook "$WB"

Locate Before Editing

Use search before editing when the target is defined by visible workbook content:

univer search "$WB" West

Plain text output is one A1 reference per matched cell, which keeps shell pipelines clean. With no matches, stdout is empty and the command still succeeds. Use --json when you need match metadata, the matched cell data preview, truncation flags, counts, or the searched scope:

univer search "$WB" West --sheet Orders --range 'A1:Z200' --json

By default, search checks displayValue, so formatted values such as dates are searchable by the same strings a user sees in the sheet. Use --type rawValue for underlying numeric/string values such as spreadsheet date serials, and --type formula for formulas:

univer search "$WB" 2024-01-01
univer search "$WB" 45292 --type rawValue
univer search "$WB" SUM --type formula --json

Useful narrowing options:

• --sheet <name> may be repeated.
• --range <A1> may be repeated; unqualified ranges require a --sheet.
• --case-sensitive and --whole-cell tighten matching.
• --max-results limits returned matches; truncation is reported on stderr for text output and in JSON fields for --json.
• --max-cell-value-length bounds previewed cell data in JSON.

If search fails, read stderr for the diagnostic message before changing approach. If the target is not content-defined, inspect a bounded range and derive the edit boundary from visible headers and sample rows:

univer inspect range "$WB" --range 'Sheet1!A1:D20'

Pipe Out Through Shell Tools

Use pipe out when the shell can reduce or reshape rectangular data before the agent reads it. Prefer TSV for awk, JSON for jq, and --type rawValue when formatted display text is not safe enough for comparisons.

univer pipe out "$WB" --range 'Sheet1!A1:D4' --format tsv > ./orders.tsv
awk -F '\t' 'BEGIN{OFS="\t"} NR==1 || $2=="West" {print $1,$3}' ./orders.tsv > ./west.tsv
sed -n '1,5p' ./west.tsv

Pipe In Generated Table Data

Write only a known matrix into an explicit, sheet-qualified range. Make pipe in the terminal stage of a pipeline unless you intentionally want its success summary downstream.

univer pipe in "$WB" --range 'Sheet1!F1:G3' --input-format tsv --data-file ./west.tsv
univer inspect range "$WB" --range 'Sheet1!F1:G3'
univer pipe out "$WB" --range 'Sheet1!F1:G3' --format tsv

Verify headers, sample rows, and key columns. Row count alone is weak evidence because shifted columns can still preserve row count.

Run A Bounded Workbook Script

Use run --file for workbook-native logic that does not fit inspect, search, pipe, or export. Check univer help run and the relevant univer help run <topic> manual before using unfamiliar APIs.

cat > ./review.js <<'JS'
() => {
  const workbook = univerAPI.getActiveWorkbook();
  const sheet = workbook.getSheetByName("Sheet1");
  if (!sheet) return { success: false, error: "Sheet1 not found" };

  sheet.getRange("I1:J3").setValues([
    ["metric", "value"],
    ["west_orders", 2],
    ["reviewed", "yes"],
  ]);

  return { success: true, changedRanges: ["Sheet1!I1:J3"] };
}
JS

univer run "$WB" --file ./review.js
univer inspect range "$WB" --range 'Sheet1!I1:J3'

run scripts should:

• wrap code in () => { ... } or async () => { ... }
• return a plain object with explicit success or error fields
• use explicit workbook, sheet, and A1 range boundaries
• prefer A1 notation for fixed workbook-facing locations
• remember numeric coordinate overloads are 0-based
• use documented facade builders for conditional formatting instead of editing internal rule model shapes
• use official enum references for conditional formatting color scales, data bars, and icon sets: ConditionFormatIconSetTypeEnum supplies setIconSet().iconConfigs[].iconType, and ConditionFormatValueTypeEnum supplies value config type values
• use documented chart builders and worksheet chart APIs from univer help run charts instead of editing chart resource internals
• use documented shape builders and worksheet shape APIs from univer help run shapes instead of editing drawing or shape resource internals
• use documented floating image builders and worksheet image APIs from univer help run images instead of editing drawing or resource internals
• wait for formula calculation with the documented formula wait API before reading same-run computed results
• prefer --file for scripts beyond a short one-liner

Create Or Maintain Charts

Use univer run for workbook-local charts and univer view for visual inspection. Command-line verification should read facade state such as sheet.getCharts(), chart.getChartId(), chart.getRange(), chart.getSeriesData(), and chart.getCategoryData().

univer help run charts
univer run "$WB" --file ./create-chart.js
univer view "$WB" --open --json

In scripts, seed or choose a source range, configure sheet.newChart(), call build(), then insert it with sheet.insertChart(chartInfo). Use chart.updateRange() or sheet.removeChart(chart) for maintenance.

Special chart types have stricter source shapes:

• Most charts use a category-plus-series table, for example month, sales, cost.
• Relation charts require a node/type matrix: first column is node, second column is type/category, remaining columns are the numeric relation matrix. For N nodes, use N data rows and N + 2 columns.
• Sankey charts require a source, target, value edge list. The third column must be numeric; avoid reverse edges that create circular Sankey data.
• Bubble charts need numeric x, y, and size columns.
• Heatmap charts use the first column as y-axis labels, remaining headers as x-axis labels, and remaining cells as numeric heat values.

Create Or Maintain Shapes

Use univer run for workbook-local shapes and connectors and univer view for visual inspection. Command-line verification should read facade state such as sheet.getShapes(), shape.isLineShape(), shape.getShapeId(), shape.getShapeType(), shape.getPosition(), shape.getSize(), shape.getStartConnectInfo(), and shape.getEndConnectInfo().

univer help run shapes
univer run "$WB" --file ./create-shapes.js
univer view "$WB" --open --json

In scripts, configure sheet.newShape(), call build(), then insert it with sheet.insertShape(shapeInfo). Use sheet.newConnector() for connector lines, sheet.connectShapes() to attach connector endpoints to facade shape objects from the same worksheet, sheet.newShape(existingShape) with sheet.updateShape(updatedShapeInfo) for updates, and sheet.removeShape(shape) for deletion.

Use univerAPI.Enum.ShapeTypeEnum with setShapeType(). Common starts are Rect, RoundRect, Ellipse, Diamond, flowchart values such as FlowchartProcess, and connector values such as StraightConnector1, BentConnector3, or CurvedConnector3. Use shape facade enums for fill, stroke, dash, cap, join, and arrows: ShapeFillEnum, ShapeGradientTypeEnum, ShapeLineTypeEnum, ShapeLineDashEnum, ShapeLineCapEnum, ShapeLineJoinEnum, ShapeArrowTypeEnum, and ShapeArrowSizeEnum.

The shapes topic covers workbook-local floating shapes and connectors only. univer run does not export shape images, perform browser screenshots, or provide an interactive shape editor.

Create Or Maintain Floating Images

Use univer run for workbook-local floating images and univer view for visual inspection. Command-line verification should read facade state such as sheet.getImages(), sheet.getImageById(id), image.getId(), image.toBuilder().getSource(), image.toBuilder().getSourceType(), and update or delete return values.

univer help run images
univer run "$WB" --file ./create-image.js
univer view "$WB" --open --json

In scripts, configure sheet.newOverGridImage(), call buildAsync(), then insert it with sheet.insertImages([image]). Use image.toBuilder() with sheet.updateImages([newImage]), direct FOverGridImage methods such as setSizeAsync() or setPositionAsync(), or sheet.deleteImages([image]) for maintenance.

Use univerAPI.Enum.ImageSourceType.URL for HTTP(S) image URLs and full data URLs, ImageSourceType.BASE64 for raw base64 payloads, and ImageSourceType.UUID only for existing Univer-managed image or file UUIDs. For predictable report placement, start with univerAPI.Enum.SheetDrawingAnchorType.Position.

The images topic covers floating images only. It does not cover cell images, floating DOM, screenshot export, local image upload helpers, or a top-level univer image command.

Preview Locally

Use preview when visual confirmation helps. Check the current agent tool surface first. If a browser tool is available, run univer view "$WB" --no-open --json and open the returned URL with that browser tool. If no browser tool is available, use --open --json; --open uses the OS browser opener, not an agent runtime's built-in browser. The CLI returns a prepared URL and diagnostic if the browser cannot be opened automatically. Use --no-open --json in known headless, remote, CI, server, or no-browser environments when you only need the URL. The server process remains active until stopped.

# Agent runtime with a browser tool:
univer view "$WB" --no-open --json

# No browser tool / local desktop handoff:
univer view "$WB" --open --json

# Known headless, remote, CI, server, or no-browser environments:
univer view "$WB" --no-open --json

When a human submits review feedback in the local viewer, read it without reopening the browser:

univer view comments "$WB" --json
univer view comments --session "<session-id>" --all --json

By default, view comments returns actionable submitted comments that are not resolved. Use --all when you need pending, submitted, and resolved comments for audit context. These are local viewer review comments, not workbook-native cell notes or collaboration thread comments; the command is read-only and does not start a host, open a browser, create a session, or mutate the workbook.

Use univer help view for port and browser-opening options.

Version Verified Changes

Check status before committing. Commit only after workbook-visible verification.

univer status "$WB"
univer commit "$WB" --message "Update review ranges"
univer status "$WB"

commit creates a local changeset from current local mutations. It does not push to a remote.

Use restore when current uncommitted workbook mutations should be discarded while preserving local commits and synced history.

univer status "$WB"
univer restore "$WB"
univer status "$WB"

Use reset --soft HEAD~N to remove the last N local unsynced commits and restore their mutations as uncommitted local mutations. Use reset --hard HEAD~N to remove the last N local unsynced commits and discard current uncommitted local mutations.

univer status "$WB"
univer reset "$WB" --soft HEAD~1
univer status "$WB"

univer reset "$WB" --hard HEAD~1
univer status "$WB"

reset only accepts HEAD~N targets and only operates on local unsynced commits. It does not rewrite synced changesets or remote history.

Clone, Pull, And Sync

Use clone when a remote workbook unit already exists and you need a new local package path. The target .univer path must be nonexistent or empty.

WB=./budget.univer
univer clone "$WB" --unit-id unit-remote --json
univer status "$WB"
univer inspect workbook "$WB"

Use pull when you only need missing remote changesets for a package already bound to a remote unit. Use sync to sync local and remote versioning state.

univer status "$WB"
univer pull "$WB"
univer status "$WB"

univer commit "$WB" --message "Update review ranges"
univer sync "$WB"
univer status "$WB"

sync creates the remote workbook first when the package is still local-only. It pulls remote changes and pushes local changesets, but it does not push uncommitted local mutations. Remote endpoints come from collaboration.defaultRemote and collaboration.remotes.<name>.url.

Export Handoff

Export after inspection proves the workbook state. Then prove the handoff file exists and, when useful, can be read back.

univer inspect workbook "$WB"
univer export "$WB" ./handoff.xlsx --json
test -s ./handoff.xlsx
univer import ./handoff.xlsx ./handoff.univer --json
univer inspect workbook ./handoff.univer

Use .xlsx for Excel handoff when workbook interoperability matters. Use CSV only when plain rectangular data is enough for the handoff.

Shell-Native Rules

Use shell tools to reduce large ranges before bringing data back to the agent. pipe out should produce clean data; diagnostics and help belong outside the data stream.

• Keep ranges explicit and sheet-qualified.
• Quote the full A1 range string, especially for non-English or shell-sensitive sheet names.
• Prefer TSV for awk and JSON for jq.
• Stage intermediate files when you need a stable preview or assertion.
• Make pipe in the usual final pipeline stage.
• Verify with inspect range or pipe out after every writeback.

Avoid pnpm dev -- ... in clean pipeline examples. The pnpm/tsx wrapper can print logs to stdout and corrupt streamed data. Use the installed univer/unv executable or another entrypoint you have proven emits clean stdout.

Gotchas

• manifest.json is metadata only. It does not prove sheet names, formulas, changed cells, or handoff correctness.
• Package contents are not a meaningful way to infer spreadsheet data. Use public CLI reads instead.
• Local file identity is the workbook path, such as ./budget.univer, not unitId, sessionId, or manifest ids.
• Command success is not enough after import, mutation, export, or handoff. Verify workbook-visible state.
• A non-zero exit means the operation failed. Read stderr for the diagnostic, usage, and retry guidance.
• search may be unavailable or limited in some installed versions. Fall back to bounded inspect range.
• Quote the full range: --range 'Sheet1!A1:J20', not just the sheet name fragment.
• Shell row counts can pass while headers, columns, or keys shift. Check headers, samples, and key columns together.
• pipe in writes parsed matrix data and reports a summary; it does not echo input.
• view is readonly preview. Do not treat it as mutation verification unless the task is visual review.
• Charts are maintained through univer run and the Pro Charts facade. Do not edit chart resource internals or expect run to export chart images.
• Shapes are maintained through univer run and the Pro Shapes facade. Do not inspect private drawing resource storage or expect run to export shape images.
• Floating images are maintained through univer run and the Sheets Drawing facade. Do not invent a top-level univer image command or inspect private drawing resource storage.
• commit is local only; use sync to push local changesets.
• restore discards only uncommitted local mutations; it does not remove local commits.
• reset is local-only and limited to HEAD~N over unsynced local commits. Do not use it as a remote revert or force-push workflow.
• sync does not push uncommitted local mutations. Commit verified workbook changes first.
• If sync reports an invalid remote binding, stop and diagnose the package or remote setup.
• pull requires a package already bound to a remote unit. Use sync for first remote creation or clone --unit-id for an existing remote unit.
• clone replaced older remote binding wording. Do not use or invent a bind command.
• If runtime-backed commands fail to start, inspect univer daemon status before retrying blindly.
• If workbook-visible reads disagree with package metadata, trust workbook-visible reads first.
