How XLS to ODS Conversion Works
XLS is a spreadsheet format: it stores data in the XLS format. ODS is a spreadsheet format that stores data in the ODS format. This conversion changes the file's encoding, compression method, and supported feature set. Cell values and structure are preserved; formulas are evaluated to their computed values in plain-text target formats. Converting between these two formats is common when the source application does not support ODS natively or when the target platform only accepts ODS. 1converter processes this conversion server-side using open-source tools. Files are transferred over HTTPS, converted on secure cloud servers, and automatically deleted after 24 hours.
