Frequently asked questions
- Why convert CSV to .xlsx instead of just opening it?
- Opening CSV directly in Excel often breaks encoding, dates and leading zeros. A proper .xlsx workbook avoids the import wizard entirely.
- Is this conversion free?
- Yes, CSV to Excel is completely free on the web with no limits. Files over 20MB are a Pro feature.
- Is my data uploaded anywhere?
- No. The workbook is built locally in your browser — exports with sensitive data stay on your device.
