The .spdesignxoml file extension is related to SharePoint Designer, a specialized HTML editor and web design program used to create and modify Microsoft SharePoint sites and web pages.
SharePoint Designer also uses these files for workflow definitions associated with SharePoint sites. Office SharePoint Designer runs on Microsoft Windows.
Open the file with Office SharePoint Designer on Microsoft Windows, preferably in the SharePoint environment and project from which it originated. The file may also be readable as XML in a text editor, but that will not provide the workflow-design features needed to manage it safely.
These files are not normally converted directly to another format. To use the workflow in another workflow system, examine its definition and recreate the workflow using the target system's tools.
