Facebook Group Members Scraper

Script to scrape Facebook group members and export them into a CSV file. This Facebook Group members extractor works in the browser, without installing an extension or using a proxy. Just copy-paste the script into your Chrome console.

How to run the Facebook Group Extractor script

1. Go to a Facebook group page
2. Open Chrome Developer Console
3. Copy Paste the following code into the console. It will add a "Download 0 members" button. Important: Copy/Paste before moving to the "People/Members" tab
4. Click on the "People" tab of the group page
5. Scroll to load new members that will get scraped by the script. The button counter increases with new members scraped.
6. Once done, click on the "Download X members" button to download the generated CSV file
7. The profiles are kept in a cache until you click the "Reset" button. Thanks to this cache, the extracted profiles are still available if your browser "crashes"

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.

Manage your Facebook leads and enrich them with LinkedIn Profile

Use Facebook members profiles to build a leads database. Filter and segment leads to find the most relevant leads to contact. Then, enrich Facebook members with LinkedIn profile and email address. Follow this step-by-step tutorial to scrape Facebook members and find their LinkedIn profiles.

Find the email address for Facebook Group members

To be clear: there is no direct way to get the email address from Facebook. But we can use the name, the company name, or the LinkedIn Profile URL to find an email address! Read our guide to scrape Facebook Group Members and find their email address.

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.
• What is the "Reset" button?
  • The profiles are stored in a cache in your browser. The cache is kept if your browser restarts the page (intentionally or after a crash). When you copy/paste the script, it loads the previous profiles from the cache. The "Reset" button clears the cache.
• Is it free?
  • The script is free and open-source. You can also clean and parse the data to get only members with a Company name with a free account on Datablist. To perform a LinkedIn Profile lookup or to find an email address you have to subscribe to a paid account on Datablist. Those enrichments rely on external APIs.

How to build it locally

yarn install
yarn build

The generated script is located in dist/main.min.js.
