If a transaction description on your Česká spořitelna statement is long enough to wrap across two or three lines, it still needs to land in a single row once converted. When transaction descriptions run long and wrap across several lines, ordinary conversion tools often break each wrapped line into a separate fake row. The engine reads rows as the statement printed them: a line belongs to the transaction above it until the next date or amount signals a new row. Every multi-line description stays intact.
If your Česká spořitelna statement runs to several pages, uploading it starts the same layout detection Convert·Into applies to any statement document, page by page. The engine does not care how many pages a statement runs across. It processes the document end to end, extracts the transaction table, and then verifies the running balance against the final closing figure printed on the statement. If a row does not add up, that row is flagged for review; the rest of the file remains clean and ready. After review, you map the columns the engine found into the fields you need and export to Excel, CSV or QBO.
