About converting XLSX to ODS
XLSX and ODS solve different problems, which is why this conversion is so common. Our converter reads the structure of your XLSX 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.
XLSX is the spreadsheet format used by 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.
