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.

Frequently Asked Questions

Your data never leaves your device. All files are processed entirely in your browser using client-side JavaScript - no data is stored on our servers or sent anywhere. There's no account to hack, no database storing your files, and no API connections to your bank or accounting software. You upload, convert, download, and we forget it immediately.
No payment or signup required. You can upload your file, see a free preview of the conversion results, and verify everything looks correct before paying anything. If it doesn't work for your files, you haven't wasted any money. We only charge when you're satisfied and ready to download the final converted file.
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.
First transactions are free to preview. Full conversions use credits based on transaction count.
Your file is processed entirely in your browser. No data is uploaded to our servers.
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.
