About:
QuickJSON is a macOS Quick Look plugin that renders JSON files in a human-readable, syntax-highlighted format directly in Finder. It eliminates the need to open large JSON files in a text editor, providing instant visual parsing. This tool is ideal for developers and data engineers who frequently inspect API responses, configuration files, and data exports.

Key Features:

Instantly previews JSON files in Finder using the spacebar
Provides syntax highlighting and indentation for readability
Handles large files efficiently without opening a separate application
Simple, lightweight integration into the macOS workflow

Use Cases:

Inspecting API response logs or JSON payloads without a code editor
Validating the structure of large configuration or data export files

Alternatives:

QLStephen – A generic Quick Look plugin for plain text files, but lacks specific JSON formatting and highlighting.
VS Code – A full-featured editor that can open JSON, but is heavier and slower than a dedicated Quick Look plugin.
