cdx to eps conversion represents export of CorelDRAW compressed drawings (.cdx) to Encapsulated PostScript format (.eps), typically done for printing on physical printers or to exchange the graphics to another software.
We do not have information about any software other than CorelDRAW that can work with or export CDX format, so it's not like there is alternative to that. You can always reach out to Corel support or community if you are need of further assistance for CDX format support.
