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.

Coinbase Transactions Validation Questions
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?
You can preview Coinbase Transactions validation results for free — no signup needed. Full validation reports use credits based on row count.
What happens to my Coinbase file during validation?
Your Coinbase file is validated entirely in your browser — nothing is uploaded to any server. The Coinbase Transactions validation runs client-side using JavaScript.

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.
Why Validate Before Converting?
Coinbase Export Variations
Coinbase has multiple export types (Transaction History, Tax Reports, Advanced Trade).
Each has different column names and formats. Using the wrong export type causes conversion failures.
Validating first ensures you have the Transaction History export with required crypto and fiat columns.
What This Tool Checks
We validate your Coinbase export against the expected schema:
- Required columns present (Timestamp, Transaction Type, Asset, Total)
- Timestamp format valid (ISO 8601 UTC)
- Asset symbols valid (BTC, ETH, USDC, etc.)
- Transaction types recognized (Buy, Sell, Send, Receive, Convert)
- Amount values numeric
You get a detailed error report identifying issues before conversion.

Plus, you get instant browser-based conversion without installing Python or managing dependencies.
