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.

I’ve been using the heck out of this lately so decided to go for the paid version even though I don’t particularly need the extra features. This app has saved me a ton of time. It’s great looking through the JSON on my iPad while coding on my MBP.

It would be nice to have editing capabilities in Jayson because the app is a beautiful way of visualizing JSON and the navigation makes it easy to traverse files, so it would definitely do a lot with editing.
