When your Citibank Canada 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 pages arrive as images, not as a tidy data table. The engine still reads them: optical character recognition extracts every transaction line, so a paper statement that was photographed with a phone or run through a desktop scanner becomes a structured record with the same fields as a file exported from online banking.
Whatever the running balance looks like on your Citibank Canada statement, Convert·Into checks it against the statement's own printed closing figure before you export anything. Every row's running balance is verified against the statement's own printed closing figure. The arithmetic is checked line by line. A 3 misread as an 8, a row that was skewed too far for the scanner to catch, a credit posted as a debit: each causes the balance to break at the point where the error entered. The row is flagged for review rather than stopping the entire job, so you correct a single line and the rest stays clean. The verified file is then mapped to Excel columns, a CSV, or a QBO-ready layout and exported with the same closing balance that was printed at the bottom of the source page.
