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.

– Support opening JSON Lines, NDJSON, and plist files as well.

While OK JSON is a JSON formatter to the core, the Scripts feature also makes it a text-processing tool.
