When a BDO statement you need to convert spans more than one page, Convert·Into merges every page into a single transaction table rather than treating each page as its own file. When a statement runs several pages long, the platform reads across page breaks without skipping a line. It joins the transaction table end to end so the exported file is a single continuous ledger, not a set of fragmented sheets.
If the running balance on your BDO 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. The closing balance the statement prints on its own final page is the figure that matters. As the engine extracts each row, it recalculates the running balance line by line and compares it against that printed closing figure. If a single row does not add up, it is flagged for review; the rest of the file is held intact. That means a misread in one entry does not force you to recheck every other transaction, and you can trust the export to match the document's own closing number before it enters your books.
