Group Members Extractor tutorial with screenshots

Open Chrome Developer Console

To open the Chrome Developer console on Chrome, use the keyboard shortcut Ctrl + Shift + I (on Windows) or Cmd + Option + I (on Mac).

Copy Paste the script

Select the "Console" tab and copy-paste the script from above. Facebook shows a warning message in the "Console" asking not to paste a script from a non-trustworthy source. It's true! And if you don't trust this script, stop here. Read the source code to understand what this script does.

Click on the "People" tab and scroll to load new members

In the Group Page, go to "People" and scroll to the bottom of the page. If the counter in the button text increases as your scroll, it's working!

Export members in CSV format

Once finished, or to perform "export checkpoints", click the button "Download X members". A Download window will prompt asking where to save your CSV file.

Edit and view your CSV file

To load and view the CSV file, use Datablist.com or any spreadsheet tools.

FAQ

• How to remove the "Download" button?
  • Just reload your Facebook page. Any javascript code added in Chrome Developer Console will be removed.
• How many members can be extracted for one group?
  • Facebook loads a maximum of 10k profiles in the "People" tab. We recommend extracting new members on a regular basis. And then, consolidate all your Facebook profiles in a single list using Datablist.com.
• Can I extract members from different groups at one time?
  • Yes. The exported CSV contains a "Group Id" attribute. Load members from one Facebook group, go to another group page (without reloading your page), load members, and click "Download". Members extracted from both groups will be in a single CSV file with different "Group Id" values.
