Whichever order your Federcasse statement prints its columns in, each one still has to land in the right place once it reaches a spreadsheet. The statement's transaction table is identified automatically, and every column the document contains is placed into the correct field in the export layout: date, description, debit, credit and any extra reference columns the source provides. Nothing is merged or left behind. You control the final mapping before export, so the column order matches exactly what your ledger or accounting package expects.
If the running balance on your Federcasse 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. Each row's running balance is recalculated from the transaction amounts and checked against the running-balance figure printed on the original statement. Every line that does not add up is flagged for review individually, so a single OCR slip or a shifted digit in one row never forces you to redo an entire file. The process confirms that the closing balance in the converted output matches the printed closing balance on the statement document before you download, giving you a clean, verifiable file you can hand straight to reconciliation.
