Claude skills for spreadsheets: before you install one

Is there a Claude skill for spreadsheets?

Yes: 343 public skills from 199 GitHub repositories mention spreadsheets. The best-known ones named for it are xlsx (anthropics/skills, ★ 185k), recipe backup sheet as csv (googleworkspace/cli, ★ 32k) and sn da non spreadsheet analysis (OpenSenseNova/SenseNova-Skills, ★ 6k). Stars belong to the whole repository, not to one skill.

How do I add xlsx to Claude?

For spreadsheets, copy the xlsx folder from anthropics/skills (the folder that holds SKILL.md) into ~/.claude/skills/ to use it in every Claude Code project, or into .claude/skills/ for one project. For the Claude apps, upload the zipped folder as a custom skill instead.

Are there spreadsheets skills in other languages?

No: 4 of those listed, such as sn da non spreadsheet analysis and TypeScript 인터페이스 순서 기반 xlsx 엑셀 다운로드 구현, are written mainly in Chinese, Japanese, Korean or Russian rather than English, though the spreadsheets task is the same. Claude can follow them either way, but read them before you install.

How recently were spreadsheets skills updated?

236 of the 343 spreadsheets skills sit in repositories that changed in the 30 days before 31 Oct 2026.

Are spreadsheets skills safe to install?

Installing a spreadsheets skill means Claude will follow its instructions and may run its scripts, so read SKILL.md and every script first: for xlsx, that is everything in the xlsx folder. Watch for downloads, commands that send data out, invisible characters, and text telling Claude to keep something from you.
