ExcelMcp 2.3.12

Let your AI assistant create and update real Microsoft Excel workbooks: cells,
formulas, Power Query, PivotTables, charts, and VBA. MCP and CLI offer the same
features. Coding agents can use either; the CLI usually uses fewer AI tokens,
though results vary by task, model, and client.

What's New

New features

  • Inspect hidden workbook information using Excel's available Document Inspector checks through MCP or excelcli. Explicitly remove findings from one selected category, with clear warnings about category-wide deletion and incomplete inspection coverage. (#1131)

Fixes and improvements

  • Report a failure when adding a PivotTable value field leaves the summary blocked with #SPILL!, instead of reporting success. PivotTable read and list results now expose the layout problem. Field changes remain available for inspection and are not automatically undone. (#1128) Thanks @copilot-swe-agent!

Get started

Requires Windows, desktop Excel 2016 or later, and a signed-in interactive
desktop session.

Where you work Setup
VS Code with GitHub Copilot Install Excel MCP Server from the VS Code Marketplace.
GitHub Copilot plugins Install excel-mcp, excel-cli, or both from Awesome Copilot.
Claude Desktop Download excel-mcp-2.3.12.mcpb below and double-click to install.
Another MCP client Set up the MCP Server.
An agent that runs terminal commands Set up the CLI.

Node.js 18 or later with npm and npx is required for the plugins, Claude
Desktop bundle, and npm installations. The VS Code extension and standalone
executables do not need Node.js or .NET. NuGet tools require .NET 10.

The plugins and VS Code extension include optional report-formatting guidance;
no separate skill download is needed. See the
installation guide for setup,
updates, and troubleshooting.

Downloads
