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:
[[["Easy to understand","easyToUnderstand","thumb-up"],["Solved my problem","solvedMyProblem","thumb-up"],["Other","otherUp","thumb-up"]],[["Missing the information I need","missingTheInformationINeed","thumb-down"],["Too complicated / too many steps","tooComplicatedTooManySteps","thumb-down"],["Out of date","outOfDate","thumb-down"],["Samples / code issue","samplesCodeIssue","thumb-down"],["Other","otherDown","thumb-down"]],["Last updated 2025-08-15 UTC."],[],[],null,["\u003cbr /\u003e\n\nImporting testers from comma-separated values (CSV) files is useful when you\nwant to grant release access to many\ntesters.
