Importing testers from comma-separated values (CSV) files is useful when you want to grant release access to many testers. This feature saves you the effort of manually entering individual tester email addresses. You can use groups to share future releases with the group you created.
After you create a group, you upload a CSV file containing tester emails in the Testers & Groups tab of the App Distribution page in the Firebase console. You then import the tester emails from the CSV file to the group. The CSV file must contain the testers' email addresses in the first column. All additional columns are ignored. For example:
firstname.lastname@example.org email@example.com,This is Ignored,This also firstname.lastname@example.org,Cal Nguyen (ignored)
To add and remove testers, see Add and remove testers in App Distribution.
