If the running balance on your Société Tunisienne de Banque 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. After the transactions are extracted, every row is verified against the printed closing figure on the statement. The running balance is checked line by line; anything that does not add up is flagged for review. No row is altered silently, and a single mismatch never blocks the rest of the file. You see exactly which entries need attention, while every other transaction remains intact and ready to use.
Whether you need your Société Tunisienne de Banque statement in Excel, CSV or QBO, the underlying extracted table stays the same; only the export step differs. The verified data can be exported in the format your next step requires. Choose Excel for a clean spreadsheet, CSV for direct import into another system, or QBO to feed your accounting package. The export uses the same column mapping you reviewed on screen, so the file you download matches what you inspected.
However your Société Tunisienne de Banque statement lays out its columns, that layout is only useful to you once it is mapped correctly into the export. Before you export, map the extracted columns into the order and naming your downstream tool expects. The engine preserves the original statement columns and lets you assign each one to the correct field in the export layout. Rearrange, rename or omit columns until the preview matches exactly what you need.
