WhatsApp let you create a group with maximum 256 members. Just in case, if you want to extract all contacts from each group then you may end up by downloading some crappy apps. If you want to extract all the contacts from the group list, you can do that without installing any third party application.
With this workaround, you can extract all contacts from a WhatsApp group to excel sheet with phone number and name of all members.
Open WhatsApp WebApp on PC
Before you start, you need A WhatsApp enabled mobile phone, A Laptop or Desktop with Firefox or Chrome browser and an active internet connection for the PC and mobile phone. We are going to use the WhatsApp web application on this workaround, that we explained in detail here.
Go ahead and open WhatsApp on your Mobile phone and go to Settings > WhatsApp Web. This will open the mobile camera to scan the QR Code. Now go to your desktop/laptop and open WhatsApp Web on your browser.
Now bring your mobile near to laptop and scan the QR code from the browser with your mobile Whats App Camera to load your whatsapp group link account on your PC. Here you can see all the chats on the left side with corresponding details on the right side.
Select the WhatsApp Group
Now, you have to select the WhatsApp group on PC that you want to extract the contacts. This will open the group chat section on the right side. Now here you need to right click on the top ribbon bar where name and details of the group are visible.
Now select Inspect element (see highlighted elements in below image). You can also perform CTRL+SHIFT+I for the same. This will open the developer’s tool in the browser. You can do many operations such as finding the name of HTML tags etc. Below image a snippet of developer tools.
