CSV to Excel Free Online
Free CSV to Excel converter — turn spreadsheet data into .xlsx files privately in your browser, no upload required. No account needed, batch conversion.
CSV files store data in plain text, which is great for compatibility but lacks the formatting, formulas and multiple sheets that Excel offers. This tool converts a CSV file into an Excel (.xlsx) spreadsheet, giving you a starting point you can format, calculate and organise further. Conversion happens entirely on your device, with no upload.
