It doesn't work with this json, there should be a way to force formatting, even if it's not detected.

I agree - i would love the option to force formatting. For me, the only way to get this extension to work is if the file extension is '.json'. For django DRF projects, you can just specify a url like mysite.com/path/to/json/?format=json and it will give you json output, but json-viewer doesn't detect it at all.
