Importing testers from comma-separated values (CSV) files is useful when youwant to grant release access to manytesters. This feature saves youthe effort of manually entering individual tester email addresses. You canuse groups to share future releases with the group you created.

After you create a group, you upload a CSV file containing tester emails intheTesters & Groups tab of theApp Distribution pagein the Firebase console. You then import the tester emails from the CSV fileto the group. The CSV file must contain the testers' email addresses in thefirst column. All additional columns are ignored. For example:

ali@example.combri@example.com,ThisisIgnored,Thisalsocal@example.com,CalNguyen(ignored)
