About this app
Argo lets you view your JSON in a way that exposes complex structures and potentially confusing API return values. Easily see the best path to your data, and quickly download and analyze API return values. If you upgrade to to the Pro version, you can also generate a Swift Codable structure with just a click, easily turning a fraught and potentially frustrating process of tedious JSON analysis into a single operation.
