WhatsApp group export guides
WhatsApp gives you no way to get a group’s member list out of it. These are the routes that exist, written out properly — including the free one, and the things each method quietly cannot do.
Start here
By destination
Excel · XLSX
Export group members to Excel
Why +919876543210 becomes 9.19877E+11, why it can lose real digits rather than just hide them, and the import path that avoids the whole thing.
CSV
Export a WhatsApp group to CSV
The column layout, E.164 numbers, and the byte-order mark that decides whether names in Hindi, Tamil or Arabic survive the trip.
vCard · VCF
Save the numbers to your phone
One file, one import, the whole group in your address book — on Android and iPhone. Plus how to take them all out again if you change your mind.
CRM
Import into HubSpot, Zoho or Salesforce
Field mapping and deduplication for a list with no email addresses in it — which is the shape of data every CRM handles worst.
The free route
Or skip all of it
GroupSync reads any group you are in and hands you a CSV, Excel or vCard file. Scanning is free; your contacts never leave the browser.
