Free tool by Clarvivo · no login
Upload a CSV to catch missing click IDs, conversion names, timezone-safe dates, duplicate identifiers and malformed values before it reaches Google Ads.
Validate a Google Ads offline conversion file before upload. We check identifiers, action names, timestamps, values and currency without sending it anywhere.
This tool answers: Will my Google Ads offline conversion file be accepted and matchable?
Enable JavaScript to run the check — the diagnosis itself is free and needs no account.
Offline conversion uploads often fail quietly in the most damaging way: the file is accepted but few rows match because IDs or timestamps are wrong.
A quick schema check is cheaper than discovering the gap after bidding has already optimized against partial data.
These answer the questions this one tends to raise.
So you can trust the result — and your developer can verify it.
Quoted fields and commas are handled before column and row rules are applied.
Every row is tested for identifiers, action name, date offset, numeric value and currency.
Clarvivo makes the acquisition-to-payment path observable before an upload becomes your only evidence.
