When your Fürst Fugger Privatbank statement arrives as a scan or a photo of the page rather than a clean export, the numbers on it are just pixels until they are extracted. Scanned or photographed statement documents are handled through optical character recognition. The engine reads the printed text on the page and identifies the transaction table by its column layout. Because the image was not generated by software, minor read errors are possible; the verification step catches these before they reach the export.
Whatever the running balance looks like on your Fürst Fugger Privatbank statement, Convert·Into checks it against the statement's own printed closing figure before you export anything. Every transaction row is checked against the statement's own printed closing figure. The engine reconstructs the running balance line by line from the opening total. If a misread digit, a skipped row, or an out-of-order entry causes the computed balance to differ from the figure printed on the document, the affected row is flagged. The rest of the file remains intact and ready for review, so a single suspect line does not block the entire conversion. Once the balance is verified, the detected columns are mapped into a clean table and exported to Excel, CSV, or QBO.
