Troubleshooting

Upload says "Invalid format"

Ensure your CSV uses UTF-8 encoding and has proper headers. Check for extra commas or special characters.

Some QR codes are missing

Check for empty rows in your CSV. Each row must have required data fields filled.

ZIP download is slow

A batch can contain up to 20 rows. Generation runs locally, so speed depends on your device and output size.
