A Commonwealth Bank statement is organised around a summary block and a balance column, which is good news for anyone who wants to check a conversion rather than trust it. There is a wrinkle worth knowing if you plan to compare a statement against an export: CommBank's own NetBank export does not use separate debit and credit columns at all — it writes a single amount column with debits as negative numbers, alongside date, transaction details and the account balance at the time. So the export and the printed statement do not necessarily look alike. The description field is where the trouble starts: CommBank passes through the payer's own reference text on Osko and PayID transfers, plus long BPAY biller names and card transaction detail with merchant location, and those routinely wrap onto a second or third line.
- Wrapped transfer descriptions are rejoined, so an Osko payment with a long reference stays one transaction rather than splitting into fragments.
- Debit and credit amounts stay in their own columns, so the direction of every withdrawal and deposit survives the conversion.
- The running balance and the opening/closing summary are both used to verify the output, and a missing row surfaces as a DISCREPANCY instead of passing silently.
- Credit card statements are handled too, though they reconcile from the printed summary rather than a per-row account balance.
