Convert your MetaMask export into a tax-ready CSV
MetaMask is a wallet, not an exchange — so its export rarely matches what Koinly or CoinTracking expect. Transfers between your own wallets get miscounted as sales and cost basis goes missing. CoinReconcile normalizes your MetaMask export into a clean, import-ready CSV and matches internal transfers so you don't overpay.

- ✕No exchange-style schema. MetaMask exports raw on-chain movements, not buy/sell rows.
- ✕Wrapped tokens & bridges. Miscategorized as disposals by generic importers.
- ✕Self-transfers taxed. Wallet-to-wallet moves counted as sales.
- ✕Gas fees everywhere. Uncounted or double-counted, distorting totals.
How to convert your MetaMask file
- 1. Export your transaction history from MetaMask (CSV or Excel).
- 2. Drop it into CoinReconcile. We auto-detect the columns, match internal transfers, and flag missing cost basis.
- 3. Download a Koinly / CoinTracking-ready CSV plus a reconciliation log, and import it into your tax software.
