A budget or a bill of quantities almost never arrives in the format the next tool needs: someone sends an Excel file and you need a CSV to import it, or the other way around.

This converter reads the file in your own browser with the same library thousands of web tools use (SheetJS) and generates the converted file right away. The original file is never sent to any server — the conversion happens on your machine.

Upload the file, check the preview, and download the result. If the Excel file has several sheets, you can choose which one to convert.
