What is an XSD File?


Question: What is an XSD File?

Did you find an XSD file on your computer and wonder what program should open it? Maybe someone emailed you an XSD file but you're not sure how to use it. Perhaps you tried to open the XSD file but Windows told you that it could not open it.

Before you can open an XSD file (assuming it's even a file format that's intended to be viewed or edited), you'll need to determine what kind of file the .XSD file extension refers to.

Answer: A file with the XSD file extension is most likely an XML Schema file.

Pattern Maker, a cross stitch program, also utilizes the XSD extension for its format.

Other types of files may also use the XSD file extension. If you know of any additional file formats that use the .XSD extension, please let me know so I can update this information.

How To Open an XSD File

The easiest way to open an XSD file is to double-click on it and let your PC decide which default application should open the file. If no program opens the XSD file then you probably don't have an application installed that can view and/or edit XSD files.

Warning: Take great care when opening executable file formats received via email or downloaded from websites you're not familiar with. See my List of Executable File Extensions for a listing of file extensions to avoid and why.

XSD files are similar in format to XML files and follow the same sort of open/edit rules since they're completely text based. Most questions regarding XSD files revolve around how to create them. I found this great blog post about creating XSD files.

SchemaViewer is a free program that will display XSD files in the proper tree format, which makes them easier to read than with a simple text viewer like Notepad.

XSD files can also be opened with Microsoft Visual Studio, XML Notepad, and EditiX Free XML Editor.

If you know anything else useful about XSD files, please let me know so I can update this page.

Tip: Use Notepad or another text editor to open the XSD file. XSD files are text-only files meaning any text editor is able to properly display the file's contents.

If you find that an application on your PC does try to open the XSD file but it's the wrong application or if you would rather have another installed program open XSD files, see my How To Change the Default Program for a Specific File Extension guide for making that change in Windows.

How To Convert an XSD File

There are two main ways to attempt to convert an XSD file to another file type:

The first option involving opening the XSD file in its native program is preferable because it's both easier and will probably result in a more accurate file conversion. Of course if you don't have a program that opens XSD files, a third-party file conversion tool (the second option) could be very useful.

Important: You cannot usually change a file extension (like the XSD file extension) to one that your computer recognizes and expect the newly renamed file to be usable. An actual file format conversion using one of the methods described above must take place in most cases.
