After connecting your number to 2Chat, all WhatsApp groups in your number will begin a synchronization process with 2Chat. Once this process is finished, you should see all of your WhatsApp groups listed in the Groups tab, together with a button to download the participants.
The exported data will be downloaded as a CSV file that you can open in Excel or any text editor. It contains the participants' numbers, profile pictures, and names, among other data.
