Open, create, read, analyze, edit, or validate Excel/spreadsheet files (.xlsx, .xlsm, .csv, .tsv). Use when the user asks to create, build, modify, analyze, read, validate, or format any Excel spreadsheet, financial model, pivot table, or tabular data file. Covers: creating new xlsx from scratch, reading and analyzing existing files, editing existing xlsx with zero format loss, formula recalculation and validation, and applying professional financial formatting standards.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# MiniMax XLSX Skill
Handle the request directly. Do NOT spawn sub-agents. Always write the output file the user requests.
## Task Routing
| Task | Method | Guide |
|------|--------|-------|
| **READ** — analyze existing data | `xlsx_reader.py` + pandas | `references/read-analyze.md` |
| **CREATE** — new xlsx from scratch | XML template | `references/create.md` + `references/format.md` |
| **EDIT** — modify existing xlsx | XML unpack→edit→pack | `references/edit.md` (+ `format.md` if styling needed) |
| **FIX** — repair broken formulas in existing xlsx | XML unpack→fix `<f>` nodes→pack | `references/fix.md` |
| **VALIDATE** — check formulas | `formula_check.py` | `references/validate.md` |
## READ — Analyze data (read `references/read-analyze.md` first)
Start with `xlsx_reader.py` for structure discovery, then pandas for custom analysis. Never modify the source file.
**Formatting rule**: When the user specifies decimal places (e.g. "2 decimal places"), apply that format to ALL numeric values — use `f'{v:.2f}'` on every number. Never output `12875` when `12875.00` is required.

How to install
mdr add martgueritainaccurate875/skills/minimax-xlsx@sha256:4ffb70af6ccd00e9The line at the top of this page pins the label v1.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
