OK JSON is a native and scriptable JSON formatter. It has excellent performance and is tightly integrated with macOS. Its main features include:

• Display JSON structure in both tree view and editor at the same time
• Drag and drop, dark mode, URL Schemes, Quick Look, extremely strong performance
• Built-in jq and JSONPath, making further JSON processing more convenient
• Save viewing history to a local database
• Use custom-based JavaScript scripts to process JSON strings
• Quick Look extension and an officially produced Raycast extension, and you can even make your own with Apple Script
• All JSON strings stay local only, no more suspicious websites needed
• Also supports opening JSON Lines, NDJSON, and plist files

Although OK JSON is still essentially a JSON formatter, its scripting features also make it competent for text processing.
