**Automate Excel with AI** — A Model Context Protocol (MCP) server for comprehensive Excel automation through conversational AI.

**MCP Server for Excel** enables AI assistants (GitHub Copilot, Claude, ChatGPT) to automate Excel through natural language commands. Automate Power Query, DAX measures, VBA macros, PivotTables, Charts, formatting, and data transformations (26 tools with 234 operations).

**⚡ Powered by the real Excel engine** — ExcelMcp drives the actual Excel application through its official COM API, so it does what file-parser tools can't: run live operations (refresh Power Query, recalculate, refresh PivotTables and the Data Model, evaluate DAX, run VBA and Python `=PY()`) and edit your existing workbooks with every formula, PivotTable, chart, macro and format left intact.

**💡 Interactive Development** - See results instantly in Excel. Create a query, run it, inspect the output, refine and repeat. Excel becomes your AI-powered workspace for rapid development and testing.

**🧪 LLM-Tested Quality** - Tool behavior validated with real LLM workflows using [pytest-skill-engineering](https://github.com/sbroenne/pytest-skill-engineering). We test that LLMs correctly understand and use our tools.

**Technical Requirements:**
- ⚠️ **Windows Only** - COM interop is Windows-specific
- ⚠️ **Excel Required** - Microsoft Excel 2016 or later must be installed
- ⚠️ **Desktop Environment** - Controls actual Excel process (not for server-side processing)

> [!TIP]
> **Also building PowerPoint decks?** Check out [PowerPoint MCP Server](https://powerpointmcpserver.dev/) —
> the sister project, built the same way.

## 🎯 What You Can Do
