Here is a list of the most important things to remember when preparing a CSV file for uploading entries. You can find all details related to importing CSV files in the Add athletes from a CSV file guide.
- For words, only the first letter should be in uppercase,
 - Correct CountryCode, all of it in uppercase,
 - Correct event name in English or EventCode,
 - All cells empty below the last athlete on the list,
 - Unique EntryId for each line,
 - Correct EventStage,
 - DateofBirth in the proper format (YYYY-MM-DD),
 - No empty AgeGroup field (appropriate one or Auto),
 - If a relay event is present, add a RelayId,
 - Save the file in the UTF-8 CSV format,
 - No need to add a StartListId (if you import individual events only),
 - If using the column FullName, you should add first name + last name and not the opposite.
 - Do not add Unattached (or similar wording) to the ClubName or TeamName columns. The field should be empty if an athlete or relay team has no club/team.
