git clone https://github.com/harumiWeb/exstructExStruct — Excel Structured Extraction Engine
ExStruct reads Excel workbooks and outputs structured data (cells, table candidates, shapes, charts, smartart, merged cell ranges, print areas/views, auto page-break areas, hyperlinks) as JSON by default, with optional YAML/TOON formats. It targets both COM/Excel environments (rich extraction) and non-COM environments (cells + table candidates + print areas), with tunable detection heuristics and multiple output modes to fit LLM/RAG pipelines.
Features
- Excel → Structured JSON: cells, shapes, charts, smartart, table candidates, print areas/views, and auto page-break areas per sheet.
- Output modes: (cells + table candidates + print areas; no COM, shapes/charts empty), (texted shapes + arrows, charts, smartart, merged cell ranges, print areas), (all shapes with width/height, charts with size, merged cell ranges, print areas). Verbose also emits cell hyperlinks and . Size output is flag-controlled.
