What should I do if the uploaded .csv file is not supported?

If your uploaded .csv file is not supported in FreJun, it usually means there’s a formatting issue.

Check the File Format

• Make sure the file is saved as Comma-Separated Values (.csv) — not Excel (.xlsx) or another format.

  • In Excel or Google Sheets:
    Click File > Download > Comma-separated values (.csv)

• Verify Phone Number Formatting

  • Use international format with country code

 You can download the sample .csv file by clicking here.
