NAB's export is on the wide side. Alongside the fields you need it carries account numbers, transaction type codes, a running balance and, on personal accounts, NAB's own spending categories. None of that belongs in your accounting import, and leaving it in is how rows end up misaligned.
Open the account, go to the transaction history, set your date range, then export. Choose CSV rather than PDF: a PDF statement has to be re-typed or OCR'd, and both introduce errors a CSV export avoids entirely.
Typically: date, a signed amount, account number, transaction type, transaction details, running balance, and category fields. Dates are day-first.
| Field | Map it to |
