Convert CSV to Excel (.xlsx)

Turn a raw CSV export into a proper Excel workbook. Instead of wrestling with Excel's import wizard, get a real .xlsx with your data in clean columns, ready to sort, filter and format. The conversion happens in your browser — your data never leaves your device.

  3. Download the Excel file and start working.

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.
