Getting Started with an Agent

SheetXL gives AI agents a real spreadsheet engine: Excel-compatible calculation with 535+ functions, best-in-class .xlsx support, and a typed SDK the agent writes code against — not a fixed menu of tools.

Copy this to your agent (Claude Code, Codex, Cursor, …):

Install SheetXL skills:
npx -y skills add sheetxl/skills -g --all

Tell me 3 interesting things I can do with SheetXL.

The agent installs the skill, fetches the SheetXL engine on demand, and shows you what it can do — nothing else to set up.

Go deeper — just ask your agent​

The agent isn't only the user of the install; it's the installer. Once the skill is in, you can ask it to:

  • "Wire up the SheetXL MCP server" — audited edits, undo, and sandbox sessions. (In Claude Code there's also a one-step plugin: /plugin marketplace add sheetxl/skills then /plugin install sheetxl@sheetxl — it bundles the skill and the MCP config.)
  • "Show me this workbook in a viewer" — the agent serves the spreadsheet to a local browser link.
  • "Install the SheetXL VS Code extension" — a human in the loop: shared sessions, live highlights, and prompts.
