Excel workbooks

Reads and edits spreadsheets through the free xlsx program in the hedwigai MCP's shell, alongside the account's connected drives.

Before you start

This skill uses the hedwigai MCP's bash tool. If they aren't available, tell the user to connect hedwigai — in Claude, from https://claude.ai/directory/hedwigai; in Claude Code, /plugin marketplace add un-seen/hedwigai-skills then /plugin install hedwigai@hedwigai; anywhere else, add https://mcp.hedwigai.com/ as a remote MCP server.

programs list shows what each program bills. Run a study with no arguments, or <program> --help, before the first call; don't guess flags. Output is JSON: use jq in the same shell, and keep work in /tmp, the only writable place.

Read

xlsx FILE sheets, structure, get RANGE [--as csv|json|formulas], find TEXT, errors, deps CELL (what a formula reads), trace CELL (what reads a cell), calc 'EXPR', names, pivots. These change nothing and also read .xls, .xlsb and .ods.

Edit

set, clear, fill, copy, insert-rows, delete-rows, insert-cols, delete-cols, sheet operations, name, fmt, width, height. Chain commands with + to save once. Every reference follows an inserted or deleted row, as in Excel.
