About E164Flow.
Created by David Cvetko.
E164Flow focuses on the cleanup before a CRM import: inconsistent phone formats, missing country context, extensions and duplicate numbers. It keeps the original fields beside the results so you can review the file before importing it.
The service is operated by SData poslovne rešitve d.o.o. in Slovenia. For product questions, problems with a conversion or a feature request, email info@e164flow.com.

Your contact data stays on your device.
Reading a file, checking numbers and building an export happen inside your browser. Account sign-in, saved defaults and billing use separate network requests.
How to check during a conversion
- Open the converter with a few sample numbers.
- Open your browser’s Developer Tools and select Network. Clear the request list after the page has loaded.
- Convert the sample and inspect any request payloads. Phone numbers and file contents are not sent for processing. In a free account you can also check a file import and export.
This is a check you can repeat, not a live network meter. Loading the app, signing in or saving country and format defaults can create requests.
What the tool does
Format and validate up to 10 phone columns, review warnings and duplicate references, then export CSV or Excel with extensions in their own fields. The free account handles up to 50 rows per file; Pro raises that limit to 20,000.
E164Flow does not confirm that a phone number is active, enrich a contact or write directly to a CRM.
