Converts AutoCAD DWG files to Excel spreadsheets without needing an AutoCAD license, which is the main selling point here. It handles DWG formats from 1992 through 2026 and extracts layers, blocks, attributes, text, and geometry data into structured tables. The Python wrapper is comprehensive with dataclasses for entities, layers, and blocks, plus batch processing for entire folders. Windows only since it wraps a CLI tool called DwgExporter.exe. Useful if you need to analyze CAD data programmatically or build reports from construction drawings. The PDF export option is a nice bonus for generating sheets without opening AutoCAD.
