If the running balance on your Gatehouse Bank statement does not add up row by row, that is exactly the kind of mismatch Convert·Into is built to catch rather than pass through silently. The engine reads every transaction and independently adds up the running balance column. It compares that calculated figure against the printed closing balance on the statement document itself. A row where the numbers do not reconcile is flagged for review instead of being silently accepted. That means a single misread digit, a skipped line, or a sign that flipped from credit to debit will not corrupt the exported ledger without your knowledge.
Whichever order your Gatehouse Bank statement prints its columns in, each one still has to land in the right place once it reaches a spreadsheet. The extraction builds a clean transaction table, and you decide how its columns map into the export layout before the file is written. Date, description, debit, credit and balance fields can each be assigned to the position your accounting package or spreadsheet expects. The same statement data can therefore feed a formatted Excel workbook, a flat CSV file, or a QBO import without manual rekeying or column shuffling after the fact.
