Checks which numbers in a list actually have WhatsApp, then exports the result to Excel.
- Bulk validity check against WhatsApp
- Excel output split into valid and invalid
- Paced checking rather than a burst
- Resumable on a long list
Why I built it
Half of a typical contact list is dead numbers. Sending to all of them wastes time and, worse, raises the failure rate on the account — which is exactly the signal that gets a number restricted.
How it works
It works through the list checking each number's status through WhatsApp Web, at a controlled pace, and marks each as registered or not. The output is an Excel file split into valid and invalid so you can send to just the first group.
Store description Bulk check which numbers are on WhatsApp. Validate lists, filter by country, spot business accounts, export to Excel or CSV.
