About

spreadsheet-kit

[](https://github.com/PSU3D0/spreadsheet-mcp/actions/workflows/ci.yml) [](https://crates.io/crates/spreadsheet-mcp) [](https://www.npmjs.com/package/agent-spreadsheet) [](https://github.com/PSU3D0/spreadsheet-mcp/blob/main/LICENSE)

Spreadsheet automation for AI agents. Read, profile, edit, and recalculate .xlsx workbooks with tooling designed to be token-efficient, structurally aware, and agent-friendly.

spreadsheet-kit ships two surfaces:

| Surface | Binary | Mode | Best for | | --- | --- | --- | --- | | [agent-spreadsheet](#quickstart-cli) | agent-spreadsheet | Stateless CLI | Scripts, pipelines, one-shot agent tasks | | [spreadsheet-mcp](#quickstart-mcp-server) | spreadsheet-mcp | Stateful MCP server | Multi-turn agent sessions with caching and fork/recalc |

Both share the same core engine and support .xlsx / .xlsm (read + write) and .xls / .xlsb (discovery only).
