How to use CSV to Excel
- Add one or more CSV files.
- Choose how multiple files are combined.
- Download your Excel file(s).
Is it private?
Yes. CSV to Excel runs 100% inside your web browser. Your files are never uploaded to a server, so even we can’t see them. That makes it a safe choice for sensitive spreadsheets, contracts, and personal documents.
Frequently asked questions
Can I combine several CSVs into one workbook?
Yes — each CSV becomes its own sheet in a single .xlsx.
Is my data uploaded?
No, the conversion happens locally on your device.
