Troubleshooting
Upload fails with "Invalid format" error
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
Large batches (>1000 codes) may take time. The process runs locally, so performance depends on your device.
QR codes look blurry when printed
Increase the size to at least 300px and use High error correction level for print materials.
