Phone Number Formatter — free online
You copied a list of phone numbers from a spreadsheet or a form, and they're all over the place: some have spaces, some have dashes, some are missing the country code, and a few are just wrong. Fixing them by hand is slow and easy to mess up. We added a free tool that does it for you — Phone Formatter — right in your browser.
What it does
Paste your phone numbers, one per line, pick a default country code and the output format you want, and it gives you back a clean, normalized list. Anything that isn't a valid number gets flagged, so you can see the problems at a glance instead of hunting for them.
Nothing leaves your device
The whole thing runs inside your browser. Your numbers are never uploaded to a server and nothing is saved. When you close the tab, it's gone.
How to use it
- Open Phone Formatter and paste your phone numbers, one per line.
- Choose a default country code and the output format you want.
- Copy the clean list, and check the flagged ones for anything that needs a fix.
It's free with no limit. There are more small tools on the Apps page.
