.XSX File Extension

There is only one file type that uses the .XSX extension:

Visual Studio XML Schema Layout File

Visual Studio XML Schema Layout 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.

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.
