This direction is useful when a delivery system, editing application, document workflow, or archive expects ODS instead of XLSX. It can also help prepare a file for a different compatibility or publishing requirement.
The source format is decoded and written as ODS. The result can differ in compression, metadata, layout, color, codec, or other format-specific details, so inspect the output before using it in a final workflow.
The practical result depends on the formats and the source file. Raster images may change in compression or transparency; media may change in codec or bitrate; documents may change in layout or fonts. Keep the original when those details matter.

Add the source file and review the selected XLSX to ODS operation.

Download or continue with the converted file only after the important details look correct.
Yes. This page is for the registered XLSX-to-ODS direction. The available result still depends on the contents and features of the source file.
Check the properties that matter to your workflow, such as quality, transparency, pages, layout, duration, audio, metadata, or compatibility with the application that will open the ODS file.
Not necessarily. Format conversion can change features that the target format represents differently, so retain the original and review the converted file before publishing or sharing.
Use a readable source file, confirm that the selected direction is correct, and decide in advance which visual, structural, or media properties must be verified in the ODS output.
