The SPDESIGNLISTDATA file extension is used by Microsoft Office SharePoint Designer for data associated with SharePoint lists. The file is a supporting data file for the application rather than a general-purpose document.
SharePoint Designer is a specialized HTML editor and web design program for creating and modifying Microsoft SharePoint sites and web pages. This file can form part of the information the program uses while working with SharePoint list data.
Office SharePoint Designer runs on Microsoft Windows.
Open a .spdesignlistdata file with Microsoft Office SharePoint Designer on Windows. Such files may be supporting files used by the application and may not provide a useful view when opened directly.
Work with the associated SharePoint site or list rather than editing the file in a text editor.
There is no widely supported direct converter for the .spdesignlistdata format. The file is application data rather than a document format intended for routine export.
When the information must be reused, open the associated SharePoint site or list in SharePoint Designer or another suitable SharePoint tool and export the list data through that tool, if the required export option is available.
