Visual JSON is a simple and very easy to use JSON visulization tool for JSON API server/client developers.

Using the Visual JSON utility one can access remote or local address to JSON server and refresh its result with a click. Or just paste raw JSON value.

You also can test POST method using simple http query expressions.

Good luck for Developers.

Works well!


Does what it says it will! Shows you JSON in a descriptive format, making it easier to pick apart and reduce the number of mistakes in your own apps.

It would be nice for the app to be able to save your sessions, including Header details, as it only saves the returned JSON content of your request currently. This makes it a little irritating, having to re-enter cookie values and the like whenever you return to a coding session and need fresh data. Some syntax highlighting of the text view would also be incredibly useful.

But for free, who can really complain!

Just what I needed

Ian Bradbury

I was looking for a tool that would allow me to inspect JSON responses from various public/private web services - and this tool does just that.

Highlight features are the ability to set custom header values and the ability to save sessions for later.

Can’t beieve this was free - I’d easily have paid a few pounds.

Best free JSON explorer and formatter in the Mac App Store


If you work with JSON this is ideal. Either provide a URL with GET or POST params, or paste in your JSON text. Then you can explore the JSON with a tree, collapsing and expanding nodes, or view and copy the formatted JSON as text.

One idea for the developer to make this perfect - Support JSONP which is often used for cross domain JSON and mobile apps. But even without this, a big thank you for developing this great free app!
