How to upload CSV file to Woodpecker

I am trying to upload a .csv file. But it keeps getting rejected. What’s causing the issue?

LaytonWhitehead,

Thanks for reaching out!

Please make sure that the first cell of the CSV file is “email” and that the field names don’t include special characters.

I also attached a step-by-step instruction here

Please let me know if you have any follow-up questions!
