The extension doesn't work

[desbest]

Hello your extension doesn't work. When I open these .json files, I don't get any syntax highlighting or code beautifying/prettifying.

Are you only looking for the Content-Type HTTP header and not the file extension?

Try it yourself and test it out with these URL's
