Whichever order your Groupe Caisse d’épargne statement prints its columns in, each one still has to land in the right place once it reaches a spreadsheet. Column mapping is automatic. The engine identifies every field that appears in the statement table: date, description, debit, credit, and any supplementary columns the layout includes. Each is assigned to the corresponding column in the export template so the order, header labels and data types match what your accounting package expects. You can review and adjust the mapping before export; swapping two columns or hiding one you do not need takes a single click.
If the running balance on your Groupe Caisse d’épargne 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 running balance is verified line by line. The engine reads the closing balance printed on the statement document, then steps through every transaction row, checking that each computed running figure matches what appears on the page. A row where the numbers do not add up is flagged for review. The rest of the file remains intact, so a single discrepancy does not block progress on the full month of data.
