This is comprehensive Excel automation for Windows through MCP, exposing 226 COM operations that cover everything from basic range manipulation to Power Query M code and DAX measures. The documentation is unusually thorough about gotchas, like needing to add tables to the Data Model before creating measures, or switching to manual calculation mode before bulk writes. It shares sessions with a CLI tool, which is handy for debugging. The behavioral rules are opinionated but sensible: never ask clarifying questions when you can discover with list operations, always format numbers after writing values, prefer Excel Tables over plain ranges. If you're building Excel workflows that go beyond simple CSV exports, this gives you the full surface area of Excel's object model without writing VBA.
