Move an Excel workbook (.xlsx or .xlsm) onto Malloy - recover the model hiding in its cells, translate its formulas and pivots, and prove the numbers match against the values the file already stores. Use when a workbook is present, when a user wants to migrate or switch off a spreadsheet, and whenever a specific formula has to become Malloy - SUMIFS, COUNTIF, SUMPRODUCT, VLOOKUP, XLOOKUP, INDEX/MATCH, pivot tables, assumption cells, roll-forwards, circular references, Monte Carlo, or a Power Pi…
Works with any agent that supports SKILL.md skills.

Install
Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.
if [ -e ~/.agents/skills/'malloy-excel-review' ] || [ -L ~/.agents/skills/'malloy-excel-review' ]; then echo 'A skill folder named malloy-excel-review already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/malloydata/publisher' "$d" && git -C "$d" checkout --quiet 'bb8ce0db61c90d45273e4b65c5ccfc6475a9193a' -- 'skills/malloy-excel-review' && mkdir -p ~/.agents/skills && cp -R "$d"/'skills/malloy-excel-review' ~/.agents/skills/'malloy-excel-review' && rm -rf "$d"; fi
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/'malloy-excel-review' ~/.claude/skills/'malloy-excel-review' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
