Advanced Excel MCP

A read-only Model Context Protocol server designed to normalize messy laboratory and instrument Excel and CSV exports into clean, structured JSON tables. It handles complex spreadsheet formats including title blocks, unit rows, decimal commas, and limit of detection flags, while preserving column metadata. The server operates via stdio, does not open ports or fetch URLs, and ensures data trust by marking content as untrusted.
