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.

DWG to Excel Conversion
Business Case
Problem Statement
AutoCAD DWG files contain valuable project data locked in proprietary format:
- Layer structures with drawing organization
- Block references with attribute data
- Text annotations and dimensions
- Geometric entities (lines, polylines, arcs)
- External references (xrefs)
Extracting this data typically requires AutoCAD licenses or complex programming.
Solution
DwgExporter.exe converts DWG files to structured Excel databases offline, without Autodesk licenses.
Business Value
- Zero license cost - No AutoCAD license required
- Legacy support - Reads DWG files from 1983 to 2026
- Data extraction - Layers, blocks, attributes, text, geometry
- PDF export - Generate drawings from DWG layouts
- Batch processing - Convert thousands of DWG files
Technical Implementation
CLI Syntax
DwgExporter.exe <input_dwg> [options]
Output Formats
| Output | Description |
|---|---|
.xlsx | Excel database with all entities |
.pdf | PDF drawings from layouts |
