# exstruct

> exstruct — harumiweb-exstruct. Use this tool when you need to convert complex Excel files into structured JSON data for large language models (LLMs) or retrieval-augmented generation (RAG) pipelines. It solves the problem of extracting insights from Excel files by autonomously reading and writing Excel data via command-line interface (CLI) and model serving platform (MCP) integration. This enables AI agents to interface with Excel data, providing tables, shapes, and charts as JSON outputs.
