Coinbase Transactions CSV Validator

You can, but free scripts and AI often miss edge cases that break real-world data: missing SKUs, currency formatting quirks, tax calculation errors, or date format mismatches. We have battle-tested validators specifically designed for accounting software imports that catch these issues before they corrupt your books. Plus, you get instant browser-based conversion without installing Python or managing dependencies.

Required columns are: Timestamp, Transaction Type, Asset, Quantity Transacted, and Total (inclusive of fees). Spot Price and Fees are recommended.

Use the Transaction History CSV from Taxes → Documents. Don't use the Advanced Trade export or Tax Lot reports - they have different formats.

All Coinbase transaction types are recognized: Buy, Sell, Send, Receive, Convert, Rewards, Learning Reward, Advance Trade. The validator will identify each type.

You can preview Coinbase Transactions validation results for free — no signup needed. Full validation reports use credits based on row count.

Your Coinbase file is validated entirely in your browser — nothing is uploaded to any server. The Coinbase Transactions validation runs client-side using JavaScript.

Validation fails when the file has incorrect headers, wrong date format, or blank rows. Try opening the file in Excel and resaving as .csv to fix formatting issues.

Yes, our validator checks your file without modification. Opening CSV files in Excel can alter headers and formatting, so validation before editing is recommended.

Coinbase offers Transaction History (all activity) and Capital Gains CSV exports. Transaction History is recommended for most validation needs and includes more detailed records.

Our validator accepts files with up to 2,251 transactions. For larger histories, split your export into multiple date ranges.

Yes, we identify duplicate entries and internal transfers that may appear twice. This helps prevent incorrect accounting when importing to other platforms.
