When your Banco Desio 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. When a statement document was scanned or photographed rather than exported as a clean file, the engine applies OCR to read the text and numbers from the image. The same running-balance verification is applied to every extracted row: the printed closing figure on the document is used as an anchor, and any line where the maths does not add up is flagged for review. This means a single misread digit does not force you to rekey the entire file; you correct the flagged row and carry on.
Whichever order your Banco Desio statement prints its columns in, each one still has to land in the right place once it reaches a spreadsheet. Each column the engine identifies in the transaction table is mapped to the matching field in the export layout automatically. Date, description, debit, credit and balance are placed in the correct columns for the chosen format, without manual drag-and-drop or column renaming. You review the assignment once before exporting, and the same mapping logic is applied consistently across every document from that layout.
