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 two files or different objects in a single file.
- Use multiple splits to easily compare JSON objects in a single file or across multiple files.
- Multiple windows on the iPad allows for even more options to browse and edit JSON objects.

- 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.
- Store imported files locally, in iCloud or don't store them on disk at all.
- Short videos that help you get started with the app.
- Highlight a key from a child object of an array to quickly get an overview of the array.

Using the heck out of this

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.

Great JSON Viewer, but would be better with editing capability

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.

Super helpful, great value

The shortcuts support and url scheme is especially helpful. Can't recommend enough.

Hopefully the developer will also write a JSON editor in future.
