Not for Viewing JSON Files

As far as I can see, its impossible to open and view a JSON file in this JSON "editor". May be useful for making API calls or something, but it is useless if you just want to open a JSON file and see it nicely formatted and be able to edit the JSON. Any file I open seemed to open without error, but wouldnt display anything at all in the editor. For my intended purpose, this app is totally useless. Cutting and pasting JSON into it didnt work either. This is either for different purpose than editing JSON, or too hard to figure out. Or maybe it just completely broken.
