GS1 & Barcode Test Data Generator
Generate valid and deliberately broken GTINs and GS1 element strings to test scanners, ERP/WMS imports and label software. Reproducible, exported as CSV, JSON or TXT.
The same seed always produces the same data, so test runs are reproducible.
All GTINs use the GS1 example prefix 952, reserved by GS1 for demonstration, so they never match real products. Every category is checked in our automated tests against the GS1 Barcode Syntax Engine.
