Paused on 29 September 2026, and not for sale. Testing found it misreads Kraken and Coinbase exports and misses Binance trade history.
Do not use anything it produced for a tax return. It comes back only when it is fixed and tested against real exports.
It was meant to turn an exchange’s transaction export into a CSV for tax software. Given files in each exchange’s own column layout, it got all three wrong.
Kraken. It recognised the trades export, had no rules for reading one, and copied the columns across by position. The transaction ID landed in Date, the trade time in Quantity and the price in Fee. The ledger export came out scrambled the same way.
Coinbase. It matched column names too loosely, so Fee got the whole sale total. Cost Basis got the coin’s spot price on the day, or nothing.
Binance. A trade-history export was rejected as having no transactions in it. The transaction-history export came out scrambled, with the user ID in Date.
Cost basis is what you paid for the coins you sold. Working it out means matching each sale to the purchases behind it, and the converter never did that. It went on sale with no tests, which is how none of this was caught.
