When your Československá obchodní banka 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 and photographed statements are read using OCR, which turns the image of the page back into machine-readable text. The engine then runs its normal extraction on that text. The running-balance check applies to every statement, whether it arrived as a clean digital file or a camera snap from a mobile phone, so any number the OCR misread is caught before the data leaves the page.
Whether you need your Československá obchodní banka statement in Excel, CSV or QBO, the underlying extracted table stays the same; only the export step differs. After the transaction table is extracted and the running balance is verified, map the columns into the shape your downstream system expects. Choose the date format and number convention that match your ledger, then export the file as Excel, CSV or QBO. The export reflects the exact column mapping and sort order you select, so the file is ready to import without further rekeying or rearrangement.
