Step-by-step Guide to Scraping Facebook Groups: Bardeen
Bardeen tool offers an ingenious playbook-based approach to data retrieval. Bardeen playbook is a time-saving pre-built template that runs the automation you need in a couple of clicks. This Facebook-related workflow crawls members of the chosen Facebook group and then imports these data to Google Sheets:
- Click <Pin it> to save the playbook. If this is the first time you use Bardeen, it will be installed as a Google Chrome extension.
- Open the webpage of the Facebook group you plan to scrape.
- Specify number of pages.
- Choose the spreadsheet.
- Wait until Bardeen completes data export.
- Upon successful completion, you will see the following notification:
- Download or view the data saved to the spreadsheet.
Input requirements:
- Opened page of the Facebook group;
- Number of pages to be scraped;
Output samples:
The output of this workflow is the Google spreadsheet with the list of group members that shows their name, profile link and additional information:
Step-by-step Guide to Scraping Facebook Groups: Python-based Solution
If you are good at coding, you probably don’t need off-the-shelf tools and can rely on Python-based code samples:
- In your terminal or command prompt, run the following command to install necessary libraries. This will install the mechanicalsoup, requests, and beautifulsoup4.
- Import the libraries. mechanicalsoup is designed to automate browsers and imitate user interactions; requests — to fetch web pages with HTTP requests. BeautifulSoup parses HTML content, while json handles JSON data.
- Create a <StatefulBrowser> instance from the <mechanicalsoup> library; set up the access token and URL for the Facebook group in question:
- Use BeautifulSoup to parse the HTML content of the fetched page. With this code, you create a BeautifulSoup object from HTML content and save the parsed HTML to an output.html file.
- To find and extract the post data from the Facebook group, use specific class names to locate all post elements on the page:
- Loop through every post to extract usernames, descriptions, and number of likes:
- Save the retrieved data in a dictionary and append them to a list:
- Save the extracted data to <post_items.json>:
- Save the code in a file, for example, <scrape_facebook_group.py>, and run it from the command line. This creates two files in one directory. <output.html> contains the HTML content retrieved from the webpage of the Facebook group page, and the scraped data, such as usernames, post descriptions, and number of likes can be found in <post_items.json>:
Types of Data You Can Extract
Depending on the capabilities of the tool you use, you can extract a range of data, from a list of group members to post texts and detailed information about users.
The most common types of data you can extract:
- posts and comments;
- group member information, such as full name, unique ID, friendship status, user job, location, etc.;

Legal Considerations
Web scraping is always a gray zone in terms of ethical and legal considerations — after all, you gather someone’s data who might not be willing to share them. Besides, Facebook’s policies and terms of service clearly state that they forbid any data retrieval without they express permission, and promise all kinds of penalties for the violators.
Is Scraping Facebook Groups Legal?
The clearly legitimate approach to Facebook scraping is to obtain their permission to do that. All other methods are subject to risks of being taken red-handed, banned and charged with different penalties. So, if you plan to use any unofficial APIs or crawlers, assess all the risks you can face.
Public vs Private Groups
Since public groups contain generally available information, there’s less privacy involved and you can use different methods to scrape data from them. However, crawling data from private groups is a complex ethical dilemma. Evidently, private group members have chosen this level of privacy for some reason and are somewhat reluctant to provide their personal data to an anonymous player without even being informed.
So, the only legitimate, ethical way to scrape private Facebook groups is to obtain Facebook permission and to use their API.
Technical Aspects
Scraping is a rather complicated technical endeavor, so before you go into it, it’s worth heeding pieces of advice.
Using Proxies and APIs
Usually, no scraping project goes without static or rotating proxies. Since they ensure security and anonymity, they are employed to hide web scraping from the target platform. However, in the case of Facebook you should be extremely careful, and this social media forbids both scraping and proxies. If you still dare to go for it, keep in mind that datacenter proxies are better for small projects due to their high speed, while residential proxies are more reliable for large-scale tasks.
Handling CAPTCHAs
It’s a tricky task to bypass CAPTCHA during web scraping, and this is where rotating proxies can save the day. Change IPs to avoid detection and ban and simulate human behaviour as much as possible. Another technique to bypass CAPTCHAs is to save cookies. It reduces probability to face a CAPTCHA, since your web scraper maintains a consistent session with the website. The last but not the least, use dedicated CAPTCHA resolvers. These are tools that employ ML algorithms to decode CAPTCHAs.
