trustsaas Group Exporter for FB Add to Chrome

Free tool

Compare Two Facebook Group Member Exports

Pick an older and a newer CSV export of your group’s members. The tool matches people by User Id and lists who joined and who left. Everything happens in your browser: the files are never uploaded.

e.g. members-2026-09-28.csv
e.g. members-2026-10-05.csv

Works with CSV files from Group Exporter for FB (matched on “User Id”) and with any CSV that has a “User Id” or “Profile Url” column.

How to use it

  1. Export your group’s members once, and keep the file. Here’s how to export group members.
  2. A week later, export again.
  3. Choose both files above. The lists appear instantly.
  4. Download the new members to prepare a welcome post, then delete the old export.

The full routine is in how to track new members in your Facebook group.

Privacy

The files are read by your browser with JavaScript and never leave your computer. There’s no upload, no server and no analytics on this page. Member lists are personal data: keep them private and only use them to run your group.
