Use the result well
A clear answer, with the assumptions visible
These recommendations turn the result into an operational next step without hiding the inputs behind a score.
- 1
Review every row marked Check instead of guessing the missing country.
- 2
Use E.164 for imports and messaging systems.
- 3
Keep the original column beside the formatted result until the import is checked.
How this tool works
- Parse each number with libphonenumber-js.
- Use the selected country only when the number has no country code.
- Keep invalid rows visible so they can be fixed.
