How to fix the "Invalid Header" error for CSV uploads

I tried to upload a CSV and got an "Invalid Header" error. What should I do next?

This error is usually caused by formatting or white space changes in the header of the CSV file you're attempting to upload.

You can fix this very quickly by copying the entire header row from our Sample CSV file.

  • Make sure you click on the "1" cell in the file to instantly highlight the entire row and then click "ctrl + c" on your keyboard to copy the full row, rather than highlighting the individual filled out cells) as seen in the image below:

Once you've copied this row from the Sample file, click on the same cell (1) in the file you're trying to upload and paste the original row in your file to overwrite the current header that's causing the error.

  • After you paste in the new row, make sure you save the new file with a file extension of '.csv' and also be sure that is it UTF-8 encoded.
  • From there, you can upload again and it should import successfully!
