A formatted .xlsx workbook, with amounts as numbers rather than text — so totals, filters and pivot tables work immediately instead of after a round of cleanup.
The file is generated in your browser from the converted result, which means the spreadsheet itself is never uploaded, stored or held on a server.
The most common problem with a converted statement is amounts arriving as text: they look right, sort wrongly, and sum to zero. The workbook writes them as numeric cells, with dates as dates.
Every conversion is reconciled before you see it: the running balance is checked row by row, or — when the statement never prints one — the opening balance plus every transaction is checked against the closing balance. If the statement gives us nothing to check against, we say so instead of showing a green tick.
A batch can be exported as a single workbook with a sheet per statement, or as one combined sheet with a column identifying the source file.
It is a standard .xlsx file, readable by Excel, Numbers, LibreOffice and Google Sheets.
