Coinbase transaction exports are notoriously inconsistent — missing cost basis data, duplicated sends/receives, ambiguous transaction types. Running them through the validator before import catches the gaps my tax software would choke on. Saved me from filing 3 amended returns last season.

Which Coinbase export should I use?
Use the Transaction History CSV from Taxes → Documents. Don't use the Advanced Trade export or Tax Lot reports - they have different formats.
Is the Coinbase Transactions validator free?

What happens to my Coinbase file during validation?

How People Use Coinbase Transactions
A client's Coinbase export had timestamps in two different formats — half were ISO 8601 and the other half were US date strings. My accounting software silently swapped the day and month on the non-ISO rows. I only discovered it during year-end reconciliation when $14,000 in gains were assigned to the wrong tax lots. The validator would have flagged every single misformatted timestamp before any of that happened.
I exported my Coinbase history and imported it straight into my tax tool. It counted every Convert as both a sell AND a buy, doubling my capital gains. Owed $3,200 more than I should have. Now I validate first — the duplicate transaction check catches those double-counted converts immediately.
