Error importing CSV
I am trying to upload a CSV file with a date column and an engagement rate column (this column is in decimal format, e.g. 0.01). I keep getting the following error:
"Column name must contain only letters, numbers, and underscores, start with a letter or underscore, and be at most 128 characters long."
I've tried changing the date to UTC format - I just can't get this to work at all. I don't know what to do with the engagement rate column (I've removed the % from it).
Anyone else had a similar issue?
