Convert CSV to Excel online
Convert CSV to XLSX when plain-text data needs to become a real spreadsheet — for reviewing in Excel or Google Sheets, adding formulas and formatting, or sharing with people who expect a workbook instead of a raw text file.
When should you convert CSV to Excel?
- Turn an export or database dump into an editable Excel workbook
- Add formulas, formatting, and charts on top of raw data
- Open comma or delimiter-separated data without import errors
- Share a file colleagues can open directly in Excel or Sheets
Before you convert
Column types are detected automatically
Numbers, dates, and text are read from the CSV values; review the result if a column needs a specific format like leading zeros or currency.
One sheet, no extra workbook features
The output is a single-sheet XLSX. Formulas, multiple tabs, and styling can be added afterward in Excel or Sheets.
