Rename exported Klaviyo column headers to suggested Omnisend column names, for reporting or manual data preparation. Not an official Omnisend import format. It runs in your browser; only headers change.
Renamed headers do not make a file import-ready. Compare the result with Omnisend's import template and create any custom fields there first. For contact lists, check opt-out and unsubscribe status separately before importing.
