CSV to Excel (XLSX) Converter

Paste CSV data below and download an actual Excel workbook (.xlsx) - not a CSV file with the extension changed, but a real spreadsheet with proper cell types.

This matters if you’ve ever had Excel mangle a CSV’s encoding or column types on open; going through a real .xlsx export avoids that entirely.
