Frequently asked questions
Will the Excel output contain formulas?
No. In custom mapping mode, the generated XLSX stores cell values as text rather than executing formulas.
Will leading zeros in IDs survive?
CSV values such as 000142 are treated as text and can be preserved in the generated workbook.
Does it preserve original Excel styling?
No. The new workbook contains exported tabular values, not original formatting or charts.
