[Recommend] Why do I get an error when uploading my events from a CSV file?

If you need to upload your events from a CSV file, the format will need to meet the following requirements:

1. Data is delimited by a comma (,)
2. Your CSV file has to contain these columns: userToken, timestamp, eventType, eventName, objectID, with the columns header. Extra columns are ignored.
3. The size limit for the file is 100Mb.
4. You will need to set your timestamp in the extended format of ISO 8601 or RFC 3339. For example:
   
   • ISO 8601 (UTC): 2025-01-27T06:19:52Z
   • ISO 8601 with timezone offset: 2025-01-27T06:19:52+01:00
   • RFC 3339 (with milliseconds): 2025-01-27T06:19:52.000Z
5. Your CSV file should not have any unicode special characters like U+FEFF. This kind of character is sometimes added by tools like Excel and may not be visible in a regular text editor.

If your CSV file meets these requirements and you still have an error, please contact Support.
