Detailed Review

Jayson is a versatile JSON viewer and editor designed for iOS, offering a comprehensive suite of tools for managing and manipulating JSON data. This app allows you to effortlessly browse JSON files stored directly on your device, providing the flexibility to view your data either in a structured table format or as syntax-highlighted text, catering to different preferences and analytical needs. The tabbed interface enables quick switching between multiple files or different objects within a single file, enhancing your workflow efficiency. For more complex comparisons, Jayson supports multiple splits, allowing you to easily juxtapose JSON documents within the same file or across different files. iPad users can take advantage of multiple windows, further expanding the possibilities for browsing and editing JSON documents simultaneously. Jayson also seamlessly integrates with your device's clipboard, enabling you to parse text or the contents of a URL directly into JSON. Siri Shortcuts provide an additional layer of convenience, allowing you to parse JSON from text or links stored in your clipboard, with options to open the JSON in the app or preview it in an interactive notification. Share Sheet Actions facilitate parsing JSON from plain text, loading JSON from a link, and importing files as JSON, streamlining your data handling processes. The app also supports URL schemes for parsing text, loading link contents as JSON, or parsing clipboard contents. You can choose a specific location on your device to store imported files, ensuring organized data management. The highlight key feature allows you to quickly get an overview by highlighting a key from a child of an array. Short video tutorials are available to help you quickly get started with the app. Unlock additional features with an in-app purchase, including light and dark themes, visual appearance customization, and the ability to open more than two tabs. Jayson is the perfect JSON tool for developers.

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!!

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!
