What is an XSX file?

An XSX file is an XML properties file used by Microsoft Visual Studio, a Windows Integrated Development Environment (IDE). It contains layout settings for an XML schema, which is stored in an .XSD file. Previous versions of Visual Studio auto-generated XSX files when developers designed schema layouts in the XML Schema Designer interface.

XSX file open in Microsoft Visual Studio Code

The original XML Schema Designer component was included with Visual Studio 2005, but was not included with Visual Studio 2008 and later. Microsoft revamped and reintroduced the XML Schema Designer in Visual Studio 2010. However, Visual Studio 2010 and later versions do not generate XSX files.

NOTE: If you accidentally delete an XSX file while editing a schema, you can regenerate the file by closing and re-opening your schema.

How do I open an XSX file?

Because Visual Studio automatically generates and maintains XSX files, you likely will not need to open an XSX file. However, you can open an XSX file in Microsoft Visual Studio by following these steps:

  1. From the Visual Studio menu bar, select File → Open → File....
  2. Navigate to the folder containing your XSX file.
  3. Select your XSX file and click Open.

You can also open an XSX file using any XML editor, such as SyncRO Soft oXygen XML Editor.
