[!TIP] .xlsx → structured, typed, citation-ready JSON that an LLM can actually reason about. Cells, formulas, merged regions, tables, charts, conditional formatting, dependency graphs, and RAG-ready chunks — deterministic, fully tested, MIT. Raw workbook on the left ( financial model.xlsx ) → parser output on the right: 4 chunks, each tied back to an exact sheet!range, ready to cite in an LLM response. Spreadsheets are still the #1 unstructured data source in the enterprise. Feeding a .xlsx directly to an LLM loses structure (rows, formulas, merges), loses provenance (which cell said what), and blows through context windows. excel-parser turns an Excel workbook into a token-counted, source-addressable graph that drops straight into LangChain, LangGraph, CrewAI, the OpenAI Agents SDK, or any MCP-aware client (Claude Desktop, Cursor, Windsurf, Zed, …).       --- 🏁 Benchmark — excel-parser vs Docling on SpreadsheetBench Apples-to-apples on SpreadsheetBench v0.1: 912 real-world task instances curated from ExcelHome / Mr.Excel / r/excel.
