Upload a revenue-event CSV to catch malformed values, negative purchase amounts and invalid currency codes.

Upload a CSV with value and currency columns. We validate numeric revenue and ISO currency codes without sending it to an analytics or ad platform.

This tool answers: Are revenue values and currency codes structurally valid before I trust attribution totals?

Enable JavaScript to run the check — the diagnosis itself is free and needs no account.

A conversion can fire correctly while its value is formatted as text, uses the wrong currency, or omits money fields entirely.

Those structural mistakes spread into ROAS and revenue dashboards long before anyone sees an error.

These answer the questions this one tends to raise.

So you can trust the result — and your developer can verify it.

Find money columns
Common value and currency headers are normalised.
Apply deterministic rules
Each row is checked for finite non-negative value and a three-letter ISO code.

Formatted values: Currency symbols or locale formatting replace a numeric payload.
Currency mapping drift: Store and analytics configuration use different codes.

Can different currencies be valid?: Yes; use an expected currency only when one is required.
Does it correct the file?: It diagnoses invalid rows; it does not alter your source export.
