Statement balance checker
A statement proves its own completeness: each balance must equal the previous balance plus that row's amount. Paste rows from any converter, bank export, or your own typing, map the columns, and this tool recomputes the chain and reports the first break.
Runs in this browser tab. Nothing you paste or open here is uploaded.
Or open your CSV in a text editor and paste it whole. Processing is local.
Limitations
- A balance column is required; without one there is nothing to check against.
- Rows without amounts (markers, notes) are skipped; layouts that only print day-end balances are handled by accumulating between balances.
- One break is reported at a time: fix it and re-run, because everything after a break is arithmetic built on the error.
