This is the help page of "Output file format" that can be specified at the transfer destination in the transfer settings.

What is the output file format?

If the destination is file storage such as S3 or SFTP, you need to specify the format of the file to be transferred. Currently, you can choose from two types: CSV and JSON Lines. You can also make detailed settings for each format when importing files.
