There are multiple reasons why your Bank Activity file will not upload:

  1.  The file needs to be in a QFX or QBO format only. You can get this format directly from your bank or use a conversion tool, such as MoneyThumb, that changes a CSV file into a QFX or QBO
  2.  You have already uploaded the file and the system is designed to prevent duplicates
  3.  There is a period(.) in the name of the file
