quick look JSON for Mac

What this plugin does

Quick Look JSON is a macOS add-on that expands the built-in Quick Look capability so JSON files can be inspected immediately. Instead of launching an editor or browser, you can preview structured JSON data directly in Finder, giving a fast way to check contents without interrupting your workflow.

Primary advantages

• Improves developer and analyst efficiency by presenting JSON in a clear, formatted view for rapid inspection and debugging.
• Requires no extra applications or heavyweight tools, which reduces friction and saves time.
• Integrates with the system Finder experience so you can preview files as part of your normal file browsing.

Using it in practice

• Locate the JSON file in Finder.
• Select the file and press the spacebar to open the Quick Look preview.
• Inspect the formatted output and close the preview to continue working.

Alternatives and other tools

• QtSpim (free) — listed here as an alternate option.
• Other viewers or Quick Look plugins that render JSON with coloring and folding for easier navigation.
