Builds Excel charts, pivots, validation, exports, Office Scripts/Graph automation, and workbook audits. Use when automating workbooks; for plain edits prefer official xlsx skill.
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
# Document XLSX Skill - Quick Reference **Boundary:** when the official Anthropic `xlsx` skill is available, prefer it for plain create/edit, formula-first financial models, LibreOffice recalculation (`recalc.py`) and formula-error scans. Use this skill for its specialist lanes: - native charts, pivots, data validation and conditional formatting - Office Scripts, Microsoft Graph and xlwings automation - very large (`write_only`/`read_only`) files - untrusted-workbook audit and sanitising ## Core Decision Rules - **Decide the runtime first:** local file generation, cloud workbook automation (Microsoft 365), desktop Excel automation, or audit and sanitising. - **`XlsxWriter` is write-only.** It cannot open or edit an existing `.xlsx`. For "edit this workbook", use `openpyxl` (or ExcelJS in Node). Picking XlsxWriter for an edit task fails immediately. - **Table-first exports:** headers in one row, a named Excel Table, a frozen header row and bounded ranges. The table brings its own autofilter, so a separate `autofilter()` over the same range raises `OverlappingRange`. …

How to install
mdr add vasilyu1983/ai-agents-public/document-xlsx@sha256:6787c6fb6f964a85The line at the top of this page pins the label v1.1, 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.
