MiniMax XLSX Skill

Overview

Create, edit, read, analyze, and validate Excel files (.xlsx, .xlsm, .csv, .tsv) using XML manipulation and helper scripts.

Task Routing

Task	Method
READ — analyze data	`xlsx_reader.py` + pandas
CREATE — new xlsx	XML template with `create.md`
EDIT — modify existing	XML unpack→edit→pack
FIX — repair formulas	XML unpack→fix `<f>` nodes→pack
VALIDATE — check formulas	`formula_check.py`

Create a New Spreadsheet

# Copy minimal template, edit XML directly, then pack
python3 scripts/xlsx_pack.py /tmp/xlsx_work/ output.xlsx

Edit an Existing Spreadsheet

# Unpack → edit → repack cycle
python3 scripts/xlsx_unpack.py input.xlsx /tmp/xlsx_work/
# ... edit XML ...
python3 scripts/xlsx_pack.py /tmp/xlsx_work/ output.xlsx

CRITICAL: Never use openpyxl round-trip on existing files (corrupts VBA, pivots, sparklines). Use unpack → edit → pack.

Add a Column

python3 scripts/xlsx_unpack.py input.xlsx /tmp/xlsx_work/
python3 scripts/xlsx_add_column.py /tmp/xlsx_work/ --col G     --sheet "Sheet1" --header "% of Total"     --formula '=F{row}/$F$10' --formula-rows 2:9     --numfmt '0.0%'
python3 scripts/xlsx_pack.py /tmp/xlsx_work/ output.xlsx

Financial Color Standard

Cell Role	Font Color
Hard-coded input / assumption	Blue (`0000FF`)
Formula / computed result	Black (`000000`)
Cross-sheet reference formula	Green (`00B050`)

Common Pitfalls

Pitfall	Solution
Using openpyxl for round-trip editing	Use XML unpack→edit→pack workflow
Hardcoding calculated values	Every computed cell MUST use an Excel formula
Forgetting formula validation	Run `formula_check.py` before delivery
Not preserving original sheets	EDIT tasks must keep all original sheets and data

Verification Checklist

READ: Data analyzed without modifying source
CREATE: XML template used, formulas for computed values
EDIT: XML unpack/edit/pack used (not openpyxl)
Original sheets preserved in EDIT tasks
Formulas validated with formula_check.py
Output file deliverable produced
