About converting XLS to ODS
XLS and ODS solve different problems, which is why this conversion is so common. Our converter reads the structure of your XLS file and rebuilds it as a valid ODS file rather than simply renaming it, so the result opens cleanly in the apps you already use.
XLS is the older binary spreadsheet format from Microsoft Excel. ODS is the open spreadsheet format used by LibreOffice.
The converter sits in our document converters toolkit alongside PDF, DOCX, DOC, XLSX, XLS, PPTX, PPT, TXT, RTF, ODT, ODS, ODP, CSV, HTML and more. Nothing is installed, nothing is stored, and the output carries no watermark.
