The .spdesignlist file extension identifies data used by Office SharePoint Designer while working with SharePoint sites. It is an auxiliary file for the program rather than a general-purpose web page or document format.
Office SharePoint Designer is a specialized HTML editor and web design program developed by Microsoft for creating and modifying Microsoft SharePoint sites and web pages. The software runs on Microsoft Windows.
Open a .spdesignlist file with Office SharePoint Designer on Microsoft Windows. The file is intended for use by that program and may not provide useful content when opened independently.
If the file came from a SharePoint site or a Designer project, open the associated site or project in Office SharePoint Designer rather than treating the file as a standalone web page.
There is no generally useful standalone conversion for a .spdesignlist file. It is an auxiliary Office SharePoint Designer file, not a document format intended for export.
To preserve usable site content, open the associated SharePoint site in Office SharePoint Designer and export or copy the relevant pages and site resources using the options available there.
