The shortcuts support and url scheme is especially helpful. Can't recommend enough. Hopefully the developer will also write a JSON editor in future.

Searched far and wide for a simple app that would just allow viewing json in Safari similar to how it is viewed on a desktop. This app hit the mark and exceeded it! This is a life saver!!

Bravo - manipulative behavior by the one you thought wouldn’t Well done ! Bravo - manipulative behavior by the one you thought wouldn’t
All of Simon’s apps are genius and wholly unique, but Jayson will always have a special place in mine own heart as the single application which finally killed my phobia of JSON, in general. It is by far the most elegant and intelligent means of manipulating JSON dictionaries I’ve ever seen on any platform. I’ve worked with both the iOS and macOS apps, now, and both are - dare I say it - a genuine joy to use. BUY!
