Convert your Gemini export into a tax-ready CSV
Even when Koinly or CoinTracking "support" Gemini, real exports break the import: shifting column layouts, transfers flagged as sales, missing cost basis, and fee rows that don't add up. CoinReconcile turns your raw Gemini CSV or Excel export into a clean, import-ready file — with an audit log of every adjustment.

- ✕Transfers flagged as sales. Moving crypto out of Gemini to your own wallet gets counted as a taxable disposal.
- ✕Missing cost basis. Without acquisition value, the $0-basis assumption makes you overpay.
- ✕Unstable column layouts. Gemini changes export formats; importers silently misread columns.
- ✕Fee rows that don't reconcile. Separate fee lines and rounding create balance mismatches.
How to convert your Gemini file
- 1. Export your transaction history from Gemini (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.
