Create, edit, and analyze Excel spreadsheets

This skill ships only metadata — no inline instructions. See the source repo for details.

Install this skill

One command (all agents)

Runs the npx skills CLI which auto-detects every AI coding agent you have installed (Claude Code, Cursor, Codex, OpenCode, Windsurf, Copilot, and 51 more).

npx skills add https://github.com/anthropics/skills/tree/main/skills/xlsx

Alternative: shorthand form

npx skills add anthropics/skills --skill xlsx

Install to a specific agent

Pick the agent you use. The CLI writes the skill to that agent's standard skill directory.

npx skills add anthropics/skills --skill xlsx --agent claude-code

npx skills add anthropics/skills --skill xlsx --agent cursor

npx skills add anthropics/skills --skill xlsx --agent codex

npx skills add anthropics/skills --skill xlsx --agent opencode

npx skills add anthropics/skills --skill xlsx --agent github-copilot

npx skills add anthropics/skills --skill xlsx --agent windsurf

Manual install (no CLI)

Prefer to skip the CLI? Clone the repo and drop the skill folder into your agent's skills directory.

git clone https://github.com/anthropics/skills.git

cp -r skills/skills/xlsx ~/.claude/skills/

For other agents, replace ~/.claude/skills/ with their skill directory — see the full list.

Use it

Once installed, ask your agent to "use the xlsx skill" or describe what you want (e.g. "Create, edit, and analyze Excel spreadsheets"). Most agents auto-discover the skill from its SKILL.md description — no slash command needed.

Requires: Node.js 18+ for npx skills. Skill files are MIT-style permissive by default — check the source repo for the actual license.
