From the SKILL.md

# 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. - Write final artifacts under `output/spreadsh

About this skill
What does the spreadsheet skill do?

Use when tasks involve creating, editing, analyzing, or formatting spreadsheets (`.xlsx`, `.csv`, `.tsv`) with formula-aware workflows, cached recalculation, and visual review.

How do I install it?

Run `npx skills add fcakyon/claude-codex-settings --skill spreadsheet --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.

Where does this skill come from?

From fcakyon/claude-codex-settings, a repository with 967 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.

Is a popular skill a good skill?

Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
