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.
[!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
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.
| Interface | Works with | Why |
|---|
| MCP Server | Any MCP-compatible client | Tool discovery and persistent sessions |
CLI (excelcli) | Agents that can run terminal commands | Built-in help without loading MCP tool definitions, usually with fewer AI tokens |
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.
