Excel to CSV for system imports
ERP and bank upload templates often require CSV. Export active sheets without merged header rows — many import jobs fail when title rows occupy line 1.
Date and number formats
Verify date columns use ISO or locale expected by the target system after conversion. Leading zeros on product codes may drop unless the column is text in the source workbook.
Operational FAQ
Which sheet is converted?
The active or first data sheet depending on workbook structure. Remove summary tabs before upload if they are not part of the import.
