Why convert ODS to XLSX?
Both ODS and XLSX use lossless compression, so the conversion mainly changes compatibility, not quality. The main reason to convert ODS to XLSX is compatibility: XLSX opens cleanly in Excel, Google Sheets and most spreadsheet tools, while ODS doesn't always. If you're sharing a file with someone else, sending it to a tool that expects a specific format, or archiving it for the long term, XLSX is usually the safer target.
