Never opened

I installed the app in El Cap and tried to open it. There as no UI on the screen. I could see the text in the menu bar and when I tapped the ‘About’ menu, a small window appeared, but the main app never appeared. Uninstalled.

Can't figure out how to use it!?

There's no documentation with this application... and I couldn't figure out how to use it. I launched the applicaiton and no windows opened, there was no option to open a new window or open a file. I couldn't drag and drop a file on to the applicaiton even.

Would love if this would work as pictured above. Ideally, it would be great if you could use this as a service; just highlight some text, right click, and select the service to format the JSON. Even cut & paste would be nice too. Having to save your JSON as a file would not be too good.

Please update the description with instructions on how to use this app. Thanks.

Simple and sweet

You use it by clicking on the menubar icon at the top. You type in the top frame and the bottom frame shows the parsed json. It's very handly for both viewing json and writing your own adaptation for development. As you would expect, it has a very small footprint, so I just leave it open all the time. I could do without the icon cluttering up my dock, but I'm not going to ding it for that in a first version.
