Binance CSV reconciliation: why a complete export may still need review

A CSV can be complete as an export and still be incomplete as a ledger. Reconciliation is the work of connecting rows across sources and documenting the decisions that remain.

For People and accountants reviewing Binance spot history and related opening lots. · Updated 2026-08-03

What a spot CSV can and cannot prove

A spot trade export can show an execution, quantity, price, fee, and timestamp. It may not, on its own, prove the opening basis of the units sold, explain a transfer from another account, or connect a wallet movement to the right internal row.

Treat the CSV as a source record, not as a finished tax ledger. Preserve its column names and original values before creating normalized fields.

Run these checks before matching trades

The goal is to find gaps early and make them explainable to the next reviewer.

  • Confirm the export date range, account, timezone, and report type.
  • Check for duplicate order or trade identifiers and overlapping exports.
  • Separate execution rows, fees, deposits, withdrawals, and internal transfers.
  • Compare asset quantities before and after fees; do not round away small differences.
  • List opening lots that came from outside the export and attach their supporting evidence.

Keep assumptions and open items visible

When two rows appear to match, record why: identifier, asset, quantity, timing, and source file. When they do not match, record the exact missing fact. This is more useful than hiding the row inside a calculated total.

  1. 01Hash and preserve each original CSV before normalization.
  2. 02Normalize dates, symbols, and numeric precision in a separate working table.
  3. 03Map trades to deposits, withdrawals, and opening lots using source-backed rules.
  4. 04Review outliers and duplicates manually before producing a handoff.
  5. 05Export unresolved questions with their source row references.

Launch scope and safe intake

BasisRestore supports Binance CSV review case by case when the exact export contract and surrounding evidence fit the scope.
