How do I use Number Checker for WA?

Open the extension from your browser toolbar, enter or paste the user IDs or phone numbers you want to check, and click Check numbers. The extension opens WhatsApp Web automatically and starts the batch check. When processing is complete, download the results in Excel, CSV, or JSON format.
