Can you convert JNLP to XML?

QUICK ANSWER
Is it possible to convert JNLP to XML?
No - not a direct conversion.

Open the .jnlp directly in any text editor or XML editor - the content is already well-formed XML and is immediately readable. If another tool requires a .xml extension, copy the file and rename the copy; the content is unchanged.

Why convert JNLP to XML?

The JNLP specification requires the file to be a well-formed XML document with a <jnlp> root element. Both .jnlp and .xml share the same underlying plain-text XML format; the only difference is the file-type association the operating system uses. Any XML parser, validator, or editor handles a .jnlp file without modification.

How to convert JNLP to XML

Notepad FREE

Right-click the .jnlp file, choose Open With, and select Notepad or any XML-capable editor - the content is immediately readable as XML with no conversion step.

OpenWebStart FREE

If your goal is to run the application the JNLP points to, install OpenWebStart and open the original .jnlp file - do not rename it to .xml, as that breaks the file association OpenWebStart uses.

Quality & what to watch

  • Renaming a .jnlp to .xml changes only the operating system file association, not the file content.
  • Do not rename the file if you intend to run it with OpenWebStart - the .jnlp extension is needed for the file association to trigger the launcher.
  • Java Web Start was removed from Java 11 in 2018; if the JNLP no longer launches an application, install OpenWebStart as a free replacement.

Frequently asked questions

Is a JNLP file valid XML?
Yes, always - the JNLP specification requires the file to be a well-formed XML document; any XML parser or editor handles it without modification.
Can I rename .jnlp to .xml and open it in an XML editor?
Yes - the content is unchanged by the rename; the only thing lost is the OS file-type association that triggers Java Web Start.
Why does my system not recognize .jnlp files?
Java Web Start was removed from Java 11 in 2018; install OpenWebStart to restore .jnlp file handling on modern Java.
