High-volume quality control inspections require logging dozens of angular measurements per assembly. Free Online Protractor includes a structured measurement logger and data export system.
1. Logging Multi-Ray Measurements
As you add angle rays or save measurements, each entry stores vertex coordinates, ray endpoints, angle in degrees, radians, gradians, slope %, pitch ratio, custom labels, and timestamps.
2. Exporting Clean CSV Spreadsheets
Click "Export CSV" to download a tabular file ready for Microsoft Excel, Google Sheets, or MATLAB. Ideal for statistical quality control and tolerance analysis.
3. Programmatic JSON Export for CAD & GIS
Export raw JSON payloads containing vector coordinates to import directly into custom CAD scripts, Python processing pipelines, or GIS mapping databases.
Key Technical Takeaways
- Export detailed CSV logs with 8 measurement fields per row.
- JSON exports preserve full float vector coordinates for CAD integration.
- All export generation occurs locally inside the browser with zero latency.
