Parsed JSON tree will appear here
Click on objects and arrays to expand/collapse
Navigating complex nested JSON structures can be overwhelming when displayed as raw text. Our interactive JSON viewer transforms JSON data into a collapsible tree structure, making it easy to explore deeply nested objects, understand data relationships, and quickly find the information you need.
🌳 Interactive tree view - Expand and collapse nodes to explore nested structures
⚡ Instant visualization - See your JSON as a navigable tree in seconds
🔍 Easy navigation - Click to expand objects and arrays, no scrolling through walls of text
🎨 Syntax highlighting - Color-coded values make data types instantly recognizable
📊 Node preview - See item counts for collapsed arrays and objects
🔒 100% private - All parsing happens in your browser, data never leaves your device
Expand/Collapse Strategically
Click on objects and arrays to toggle their expansion. Use 'Expand All' when you need to see everything, or 'Collapse All' first then selectively expand only the sections you need to focus on.
Understand the Color Coding
Strings are green, numbers are blue, booleans are purple, null is gray, and property keys are rose/red. This color scheme helps you instantly identify data types without reading each value.
Debug API Responses
Paste API responses directly into the viewer to explore their structure. This is faster than console.log debugging and helps you understand exactly what data your frontend is receiving.
Navigate Large Datasets
For JSON with hundreds of items, collapse the root first, then expand only the paths you're interested in. The node count preview (e.g., '[50 items]') helps you understand array sizes without expanding.
Combine with JSON Formatter
Use the JSON Formatter to fix malformed JSON first, then paste into the viewer for exploration. The viewer requires valid JSON, so formatting and validation help prepare your data.
