Excel

About

Works with .xlsx, .xlsm, .xltx and .xltm files through openpyxl. You can read and write cells, formulas and dates, format ranges, manage sheets, rows and columns, add tables, charts, conditional formats and data validation, write static summary tables, and read VBA macro code (never run). Formulas are stored, not calculated, and real PivotTables cannot be created.

Runs locally over stdio with uvx: uvx excel-mcp-server stdio --allow-dir /path/to/workbooks. No sign-in or API key is needed. Access is limited to the folder you allow, formulas that reach the network or other programs are rejected, and a read-only mode is available. A Streamable HTTP mode and a Docker image also exist.
