Use when tasks involve creating, editing, analyzing, or formatting spreadsheets (`.xlsx`, `.csv`, `.tsv`) with formula-aware workflows, cached recalculation, and visual review.
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
# Spreadsheet Skill ## When to use - Create new workbooks with formulas, formatting, and structured layouts. - Read or analyze tabular data (filter, aggregate, pivot, compute metrics). - Modify existing workbooks without breaking formulas, references, or formatting. - Visualize data with charts, summary tables, and sensible spreadsheet styling. - Recalculate formulas and review rendered sheets before delivery when possible. IMPORTANT: System and user instructions always take precedence. ## Workflow 1. Confirm the file type and goal: create, edit, analyze, or visualize. 2. Prefer `openpyxl` for `.xlsx` editing and formatting. Use `pandas` for analysis and CSV/TSV workflows. 3. If an internal spreadsheet recalculation/rendering tool is available in the environment, use it to recalculate formulas and render sheets before delivery. 4. Use formulas for derived values instead of hardcoding results. 5. If layout matters, render for visual review and inspect the output. 6. Save outputs, keep filenames stable, and clean up intermediate files. ## Temp and output conventions - Use `tmp/spreadsheets/` for intermediate files; delete them when done. …

How to install
mdr add fcakyon/claude-codex-settings/spreadsheet@sha256:21d31dc4ecbbb7c9The line at the top of this page pins the label git:20260401.26dac1c, 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.
