If the running balance on your Postbank 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. Every converted file is checked against the printed closing figure on the original document. The tool reads the closing balance directly from the statement image, then verifies that every transaction line in the table adds up to that exact number. A row whose running balance does not tally is flagged for review rather than causing the whole conversion to fail: you see precisely which line needs attention, while the rest of the data remains usable. This check catches misread digits, missing rows and table gaps before the figures ever reach your accounts.
Whether you need your Postbank statement in Excel, CSV or QBO, the underlying extracted table stays the same; only the export step differs. The export step gives you a clean transaction table with columns mapped to the destination you choose. Output to Excel for manual review and formatting, to CSV for direct import into accounting platforms or custom scripts, or to QBO if the data is heading straight into QuickBooks. There is no locked-in schema: the columns you see on screen are the columns that write out, so you can reorder or rename fields to match your chart of accounts before you export.
Should a description on your Postbank statement break across multiple lines of the printed page, that line break is not the same thing as a new transaction. When a transaction description runs long and wraps across several lines on the original page, it can fool simpler parsers into splitting one row into two or three. The engine reads the table structure, not just the text, and keeps each transaction intact as a single row: a wrapped description stays in its own cell, and the amount, date and balance remain on the same line. The running-balance check confirms the row count stayed correct after extraction, so a split row does not reach your export silently.
