## What it is
A Model Context Protocol (MCP) server that lets LLM clients read and write Microsoft Excel files (xlsx, xlsm, xltx, xltm). It exposes tools for listing sheets, reading cell values/formulas with pagination, writing data, and creating sheets, distributed via npm.

## Use cases
- let Claude read and edit Excel spreadsheets
- read xlsx data from an MCP client
- write formulas into Excel files via AI assistant
- create new Excel sheets automatically
- inspect Excel workbook structure with an LLM
- automate spreadsheet tasks through MCP

## When to choose
- you use an MCP-compatible client like Claude Desktop and need Excel file access
- you want LLM-driven reading/writing of xlsx/xlsm files
- you need a lightweight npm-installable Excel MCP server

## When to avoid
- you need live Excel editing or screen capture outside Windows
- you need to process CSV or other non-Excel formats
- you don't use any MCP-capable client
