OK JSON is a native and scriptable JSON formatter on macOS. It's really fast and well-integrated with macOS.

The notable features from OK JSON are: - JSON structure in both tree view and text editor. - Drag-and-drop, Dark Mode, URL Schemes, Quick Look, and excellent performance. - Built-in support for jq and JSONPath. - Save viewing history to local database. - Process JSON string with custom scripts powered by JavaScriptCore. - Quick Look extension and official Raycast extension. Build your own with Apple Script. While OK JSON is a JSON formatter to the core, the Scripts feature also makes it a text-processing tool.
