Also couldn't open JSON files for me, so I edited info.plist to fix it. If you have that issue, you can get my fixed info.plist here:

It's just 2.5 kb, an XML document. Then show package contents on Jason.app and replace Contents/Info.plist with my file.

As for the actual review, the app is reasonably good. I like the built-in jsonlint and it's visually well executed, but not being able to copy/paste within the UI, among other limitations, keep this from being totally top notch.
