or paste them
Extra spaces, dashes or brackets are fine — they get cleaned automatically.
2 Check the settings
Contacts will be saved as “WhatsApp 001”, “WhatsApp 002”… so you can find and delete them all together afterwards.

Your cleaned numbers will appear here as you paste.
Almost there — finish on your phone:
When the share sheet pops up, tap Save to Files → pick Downloads → Save. (Or tap Mail and send it to yourself.)
Open the Files app, go to Downloads, and tap contacts.vcf. Important: open it from Files, not from the Safari download popup — the popup only shows one contact.
It opens as a full list. Tap Add All Contacts at the top, then confirm.
Open WhatsApp → New Group, search “WhatsApp”, add everyone, name the group.
Later: to remove them, open Contacts, search “WhatsApp”, and delete.
