Whichever order your Zurich Cantonal Bank statement prints its columns in, each one still has to land in the right place once it reaches a spreadsheet. Column mapping organises the extracted data into the layout your accounting system expects. The engine identifies the likely role of each column: the transaction date, the description, the amount paid out, the amount paid in. You can review these assignments and adjust them before export, so the debit and credit columns land in the right places every time.
If your Zurich Cantonal Bank statement runs to several pages, uploading it starts the same layout detection Convert·Into applies to any statement document, page by page. A statement that runs several pages long is treated as a single logical record. The engine reads through all pages, strips out repeated headers and continuation lines, and assembles one continuous transaction table. The closing balance from the final page is used for the running-balance check, and any discrepancy is flagged on the specific row where the arithmetic breaks, not on the entire document.
