Jayson is a simple yet powerful JSON viewer and editor with Siri Shortcuts, Share Sheet Actions and URL schemes. Features include: - Browse JSON files stored on your device. - Toggle between viewing JSON in a table or as syntax highlighted text. - Tabbed interface to quickly switch between files or different objects in a single file. - Use multiple splits to easily compare JSON documents in a single file or across multiple files. - Multiple windows on the iPad allows for even more options to browse and edit JSON documents. - Parse text or the contents of a URL in your clipboard to JSON. - Siri Shortcuts that parse JSON from a text or a link stored in your clipboard. The shortcuts can open the JSON in the app or preview it in an interactive notification. - Share Sheet Actions for parsing JSON from plain text, loading JSON from a link and importing files as JSON. - URL schemes for parsing a text, loading the contents of a link as JSON or parsing the contents of your clipboard. - Choose a location on your device to store imported files. - Highlight a key from a child of an array to quickly get an overview. - Short videos that help you get started with the app. Features that require the "Unlock Everything" in-app purchase: - Switch between light and dark themes. - Changing the visual appearance, including the app icon, accent color and type icons. - Opening more than two tabs.}

I’d like to request a feature: being able to collapse an object or an array: { "big_object": { /* a lot of properties here */ } }

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!!

機能がかなり網羅されており、UIも直感的でバグがなく使いやすいです 最高のツール…! 課金でテーマ変えたりできそうなので、使用頻度上がればしようかなと思います

Perfect I’m almost every way except that it turns my battery into a torch. It gets hot FAST. TAKE CARE OF THAT AND ITS AN EAAY 5 star app

Terrible file navigation. Can’t do much of anything without premium. No plain text editor. Avoid.

Good for editing .JSON files but seems to crash reliably almost every single time I try to use it. Disappointing, but it gets the job done sometimes.

I was browsing twitter and hadn’t launched this app in aged and suddenly I got a notification that Jayson has snooped into my pasteboard. Not cool, uninstalled

Works well, although have had the odd random crash. Navigation back through the json structure is fiddly on iPhone, frustratingly I keep hitting the file exit top right icon when trying to backup through the structure. I guess I need to train my brain that this app doesn’t work that way... Overall it’s a handy app that’s well worth downloading and it’s 'in app purchase' price.
