Spreadsheet skill — read, edit, create, and convert .xlsx/.xlsm/.csv/.tsv files. Trigger when a spreadsheet file is the primary input or output: editing columns, formulas, formatting, charting, cleaning messy data, or creating new spreadsheets. Not for Word/HTML/PDF deliverables even if tabular data is involved.
Works with any agent that supports SKILL.md skills.

Codex reads ~/.agents/skills directly. For Claude Code, Cursor, Copilot, Gemini CLI, Antigravity or OpenCode, also link it. For Claude Code: ln -s ~/.agents/skills/'xlsx' ~/.claude/skills/'xlsx' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
