About This Tool
Quickly convert any CSV data into a properly formatted Excel spreadsheet (.xlsx). You can either paste CSV text directly into the editor or upload a .csv file from your computer. A live preview table lets you verify the data before converting.
The tool handles standard CSV formatting including quoted fields and commas within values. The resulting Excel file preserves column structure and is compatible with Microsoft Excel, Google Sheets, and LibreOffice.
No sign-up or installation required. Your data is processed securely on the server and the output file is returned immediately for download.
