In writing about Workflow (then) and Shortcuts (now) for a living, at some point I realized that if I wanted to build more complex shortcuts to either deal with web APIs or store data in iCloud Drive, I had to learn the basics of parsing and writing valid JSON. The format is behind most of the web API-based Shortcuts I have shared here on MacStories1 and is one of the techniques I recently explained on Club MacStories when I built a shortcut to save highlights from Safari Reading List. The beauty of JSON is that, unlike XML, it's cleaner and more readable – provided you have a dedicated viewer that supports syntax highlighting and/or options to navigate between objects and inspect values. There's no shortage of such utilities on macOS, but this is the kind of niche that still hasn't been fully explored on iOS by developers of pro apps. That changes today with the launch of Jayson, created by Simon Støvring.
Readers of MacStories may be familiar with Støvring's name – he's the developer behind one of the most powerful and innovative pro apps of 2018, the excellent Scriptable for iOS. For this reason, it shouldn't come as a surprise that Jayson, a project that was born out of Støvring's personal frustration with the lack of a modern JSON viewer for iOS, has that same spark of innovation and integration with native iOS functionalities that set Scriptable apart last year. If you do any kind of work with JSON on your iPhone or iPad, you need Jayson in your life, and here's why.
