Now for the details. ODS (Open Document Spreadsheet) is the open-source alternative to XLSX. XLSX is Microsoft Excel's modern format supporting formulas, charts, and multiple sheets. Converting between these two formats lets you convert between formats quickly.

Your ODS file is decoded and re-encoded as XLSX. Converting ODS to XLSX maintains high quality with CocoConvert's optimised encoder settings.
Common misconception: ""XLSX will be smaller than my ODS file"" — in reality, xlsx uses lossless compression, so the output file is often larger than a lossy ods. if you need a small file, xlsx may not be the right choice.
CocoConvert runs entirely online — no software to install, no account to create. Your files are encrypted during upload (TLS), processed on isolated servers in Germany, and permanently deleted after 24 hours. It works in Chrome, Safari, Firefox, Edge, and all mobile browsers.
