Microsoft Office SharePoint Designer is a specialized HTML editor and web design program for working with Microsoft SharePoint sites and web pages. The .spdesignhomeop file extension identifies a file associated with that software.
Office SharePoint Designer runs on Microsoft Windows. A .spdesignhomeop file may be a supporting file used by SharePoint Designer rather than a general-purpose HTML document.
It is legacy software that is no longer actively developed, although existing SharePoint Designer files may still be encountered in older SharePoint workflows and site projects.
Open a .spdesignhomeop file with Office SharePoint Designer on Microsoft Windows. Open it from within the program if double-clicking does not work.
Some files associated with SharePoint Designer are supporting or internal files and may not open as standalone documents. In that case, open the related SharePoint site or project in SharePoint Designer instead.
The .spdesignhomeop file is normally used by Office SharePoint Designer rather than converted into another document format.
To move associated SharePoint content, use the available SharePoint Designer or SharePoint export and migration features instead of converting the .spdesignhomeop file itself.
