Why is my CSV upload failing?

The most common reason for csv upload failure are:

  1. Incorrect encoding - only supported encoding is UTF-8. Usually it can be UTF-8 with BOM or another encoding. This happens when exporting from Excel or other tools.
  2. Incorrect casing in header - the header is case sensitive.
  3. Incorrect separator - ; instead of ,
  4. Number of columns in row do not match number of columns in header.
