**Automate real Microsoft Excel with AI.** Excel MCP Server lets GitHub Copilot,
Claude, ChatGPT, and other agents control Excel through natural-language
requests—using either MCP or a token-efficient CLI.

Unlike file-parser tools, ExcelMcp drives the **actual Excel application** through
its official COM API. It can refresh Power Query, recalculate formulas, evaluate
DAX, run VBA and Python `=PY()`, and preserve PivotTables, charts, macros, the
Data Model, and workbook formatting.

**31 tools with 326 operations** cover end-to-end Excel automation.

> [!IMPORTANT]
> Requires **Windows**, **Microsoft Excel 2016 or later**, and an interactive
> desktop. It is not intended for Linux, macOS, or server-side batch processing.

## 🚀 Get Started

| Use case | Recommended path |
|---|---|
| **VS Code** | [Install the extension](https://marketplace.visualstudio.com/items?itemName=sbroenne.excel-mcp) |
| **Claude Desktop or another MCP client** | [Install the MCP Server](https://excelmcpserver.dev/installation-mcp-server/) |
| **Coding agents and scripts** | [Install the CLI](https://excelmcpserver.dev/installation-cli/) |
| **Not sure which to choose?** | [Read the installation overview](https://excelmcpserver.dev/installation/) |

Close open Excel workbooks before starting; ExcelMcp requires exclusive access
while automating them.

## What You Can Automate

- **[Data & analytics](https://excelmcpserver.dev/features/data-analytics/):**
  Power Query, DAX, Power Pivot, Excel Tables, PivotTables, and data connections.
- **[Cells & workbooks](https://excelmcpserver.dev/features/cells-workbooks/):**
  ranges, formulas, formatting, worksheets, files, calculation, and named ranges.
- **[Charts & visuals](https://excelmcpserver.dev/features/charts-visuals/):**
  charts, slicers, conditional formatting, screenshots, drawings, and sparklines.
- **[Automation & advanced](https://excelmcpserver.dev/features/automation-advanced/):**
  VBA, Python in Excel, Goal Seek, scenarios, data tables, windows, and XML Maps.

## See It in Action

[![A sales table, regional summary, and chart created in the real Excel application by Excel MCP Server](https://excelmcpserver.dev/assets/images/excel-demo-table-chart.png)](https://excelmcpserver.dev/use-cases/)

Ask in plain language:

- *"Import products.csv with Power Query and load it to the Data Model."*
- *"Create a PivotTable showing revenue by region, then add a column chart."*
- *"Use Goal Seek to find the price that produces $100,000 profit."*
- *"Show me Excel while you work."*

Because Excel performs the work, you can inspect results live and continue editing
the workbook normally.

## MCP Server or CLI?

Both entry points expose the same Core commands and behavior.

| Interface | Best for | Why |
|---|---|---|
| **MCP Server** | Conversational assistants and exploratory work | Rich schemas, tool discovery, and persistent sessions |
| **CLI (`excelcli`)** | Coding agents, automation, and scripts | One compact tool surface and substantially lower token usage |

The MCP Server calls the ExcelMcp service in-process. The CLI uses a background
daemon so workbook sessions persist across commands.
