🔒 100% Private

All parsing happens in your browser using JavaScript. Nothing is uploaded to any server. Safe for sensitive API responses.

🎨 Syntax Coloring

Values are color-coded by type: strings in green, numbers in amber, booleans in purple, and null in gray. Spot types at a glance.

📋 Copy Paths

Click any key name to copy its dot-notation path (e.g., data.users[0].name) to your clipboard. Great for API debugging.

How to View JSON Online

Paste your JSON into the left panel and an interactive tree view appears on the right. Click the ▶ arrows to expand or collapse objects and arrays. Click any key name to copy its dot-notation path. You can also drag and drop a .json file or use the upload button.

When to Use a JSON Viewer

A JSON viewer is essential for debugging API responses, exploring large configuration files, inspecting database exports, and understanding complex nested data structures. The tree view makes it easy to navigate deeply nested JSON that would be hard to read as raw text.
