If the running balance on your Cassa Depositi e Prestiti 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 row is checked automatically: the engine reads the closing balance printed on the statement and works backwards line by line to confirm the running balance adds up. A mismatch does not stop the conversion. The suspect row is flagged for review while the rest of the file remains intact, so you can spot a transposed digit or missing entry and correct it before the data reaches your ledger. No balance is rounded or estimated; the figure you see in the cleaned export is the one the engine verified against the document.
If the Cassa Depositi e Prestiti statement you have is a scanned image or a phone photo instead of an exported file, that alone does not stop Convert·Into from reading the transaction table off it. Scanned paper statements and photographs of printed pages are handled the same way as a clean digital file. The engine reads the image with OCR and extracts the transaction table, then performs the same running-balance verification that it applies to every statement. The OCR process is measured against the closing balance: anything the scan misread is flagged by the arithmetic check, so a digit that slipped past the optical read does not slip past the numbers. Upload the image, review the flagged rows, and export to Excel, CSV or QBO with the columns mapped to your standard layout.
