Why clean your list before bulk sending?
Sending to malformed or duplicate numbers wastes your daily quota and raises your spam signals — both increase ban risk. This tool normalizes every number to the international format WhatsApp expects (country code + number, no symbols), removes exact duplicates, and flags entries that can't be valid phone numbers, so your campaign list is tight before you hit send.
What it handles
- Spaces, dashes, brackets, dots and
+prefixes - Leading zeros on local numbers (08765... → 91 8765...)
00international dialing prefixes- Numbers mixed with names or other text on the same line
