Excel to CSV

Excel to CSV exports the first worksheet of an XLSX or XLS file to CSV in your browser. Later sheets are not included. Formulas are written as their values, and styling, charts, and multiple sheets are left behind.

To excel to csv, upload your file, let your browser process it locally, and download the result in a few clicks.
