Bulk Phone Number Cleaner
Paste messy CRM or spreadsheet numbers — or upload a CSV. Convert to E.164, drop duplicates, and keep only what you can actually dial. Runs privately in your browser.
Works with Google Contacts / CRM CSVs (uses “Phone … - Value” columns). Nothing is uploaded to a server.
Clean a CRM export before you dial
Spreadsheets and CRMs store the same contact as (415) 555-2671, 0014155552671, and +14155552671. This tool normalizes everything to E.164, explains why a row fails, tags country and line type, and removes duplicates after normalization so you keep one dialable copy.
Set a default country when your export uses local formats without a country code. Prefer international numbers already? Leave default country empty and require +… prefixes. For a single number, use the phone number validator.
When the list is clean, GlobCall for business lets your team call from the browser on a shared balance — useful once the messy spreadsheet work is done.
