Statement Header and Row Balance Reconciler

How to use Statement Header and Row Balance Reconciler

An extracted statement can add up while still omitting a header total or repeating a transaction. Keep independent header checks and row-level arithmetic together before correcting the source extraction.

1. Paste authorized extracted transaction metadata and separately checked statement header values.
2. Compare source-order balances, date coverage, duplicate IDs and independent header/closing deltas.
3. Check the original statement before correcting any extraction; no account, OCR service or payment is accessed.

Good to know

• Duplicate transaction IDs remain in arithmetic and exports; they are flagged, not deduplicated or called fraud.
• Blank header totals or row balances remain unknown. This is not bank reconciliation to independently verified cash or financial advice.
• Each input field is limited to 8,000 UTF-16 characters and each exact-header CSV to 100 data rows. Quoted commas/newlines and doubled quotes are supported. Unsupported controls and unpaired surrogates are refused. Decimal magnitudes are at most 999,999,999 with a smallest nonzero magnitude of 0.000000001; exponents are refused and whole counts are checked exactly. Rational results show at most 18 fractional digits and an ellipsis when more remain.
• Editable Markdown and long-form CSV both retain all summary metrics, context, detailed findings, entered source rows and scope limitations. CSV columns are Record type,Section,Source row,Field,Value; spreadsheet-looking text is apostrophe-prefixed. These are review artifacts, not proof of source truth or a completed real-world task.
• Runs deterministically in this browser. No AI, API, vendor connection, upload, outreach, calendar change, payment, storage or background monitoring. Use authorized pseudonymous records; inspect exports before sharing.
