ExcelMcp - MCP Server for Microsoft Excel

Website · Installation · Features · Troubleshooting · 2-minute demo

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.

64 MCP tools across 33 feature areas, with 437 operations, cover end-to-end Excel automation.

🚀 Get Started

For GitHub Copilot CLI, install either plugin from the Awesome Copilot Excel listings:

copilot plugin install excel-mcp@awesome-copilot
# Or, for command-line Excel automation:
copilot plugin install excel-cli@awesome-copilot

For a workbook already open in Excel, use discovery and attachment to keep working in that workbook. Excel determines whether newly opened files are read-only.

What You Can Automate

• Data & analytics: Power Query, DAX, Power Pivot, Excel Tables, PivotTables, and data connections.

• Cells & workbooks: ranges, formulas, formatting, worksheets, files, calculation, and named ranges.

• Charts & visuals: charts, slicers, conditional formatting, screenshots, drawings, and sparklines.

• Automation & advanced: VBA, Python in Excel, Goal Seek, scenarios, data tables, windows, and XML Maps.

Explore the capabilities behind all 437 operations. Current command details come from CLI help or the MCP tool descriptions.

See It in Action

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 Excel commands and behavior, so the choice is technical. Coding agents can use either one.

Both entry points run Excel commands in separate worker processes, so a blocked Excel operation does not block their basic controls. The CLI also keeps a background service running so workbook sessions persist across commands.
