XLS to CSV Converter

Description & Example

This tool converts Excel files (XLS or XLSX) into CSV format.

Simply upload your Excel file, and after a short conversion period (as indicated by the progress bar), you will be able to download the CSV version of your data.

For example, if you upload an Excel file containing your financial records or inventory data, the resulting CSV will contain the same tabular data, making it easy to import into databases or analysis tools.

About XLS and CSV

XLS (Microsoft Excel 97-2003 Workbook) is Excel's legacy binary format, still common on older systems though superseded by XLSX.

CSV (Comma-Separated Values) is plain tabular data with no formulas, formatting, or multiple sheets — just rows and columns separated by commas.

What to expect: CSV doesn't support everything XLS does, so expect formatting like fonts, styles, or embedded objects to be dropped in the conversion.
