Conversion from Excel to structured JSON (tables, shapes, charts) for LLM/RAG pipelines, and autonomous Excel reading/writing by AI agents via CLI and MCP integration.
Why this job: works in the areas we cover, but does not say which job it does
What it does
- Excel -> structured JSON. outputs cells, shapes, charts, SmartArt, table candidates, merged-cell ranges, print areas, and auto page-break areas by sheet or by area.
- Formula extraction. emits formulas_map (formula string -> cell coordinates) via OOXML or the selected openpyxl/COM path. It is enabled by default in verbose and can be controlled with include_formulas_map.
- Formats. JSON (compact by default, --pretty for formatting), YAML, and TOON (optional dependencies).
- Workbook editing interfaces. use the editing CLI for primary ExStruct edit flows, keep MCP for host-owned safety controls, and use exstruct.edit only when you need the same patch contract from Python.
