About Excel to CSV
How do I convert XLSX to CSV?
Choose or drop your XLSX file, adjust the available options, select Convert, then download the real CSV result.
Are my files uploaded?

Is FileZivo free?
Yes. FileZivo is free to use, requires no account and adds no watermark.
Which worksheet is converted?
The current V1 exports the first worksheet in the workbook and preserves its cell values.
