JSON to Graph Visualizer Tool

Transform JSON data into interactive visual graphs with nodes and connections

What is JSON Visualizer?

JSON Visualizer transforms your JSON data into interactive graph visualizations. It creates beautiful node-based diagrams that show the relationships and structure of your data, making complex JSON hierarchies easy to understand and explore visually.

How to Use JSON Visualizer

  1. Toggle "Live Preview" to see graph visualization as you type
  2. Enable "Auto Fix JSON" to automatically fix common JSON errors
  3. Paste your JSON data into the input field on the left
  4. Choose between horizontal or vertical graph layouts
  5. With live preview, the graph updates automatically as you type
  6. Without live preview, click "Visualize JSON" to generate the graph
  7. Use zoom controls to navigate large graphs
  8. Click and drag to pan around the visualization
  9. Click on nodes to see their path and type information
  10. Use fullscreen mode for better visualization of complex data

Graph Features

Root Nodes

Purple gradient nodes represent the root of your JSON structure

Object Nodes

Pink gradient nodes show JSON objects with key counts

Array Nodes

Cyan gradient nodes represent arrays with item counts

String Values

Green gradient nodes display string values with quotes

Number Values

Orange gradient nodes show numeric values

Boolean Values

Teal gradient nodes display true/false values

Null Values

Subtle gradient nodes for null values

Interactive Controls

Smooth zoom, pan, curved connections, and hover effects

Layout Options

Horizontal Layout

Displays the graph from left to right, with parent nodes on the left and children spreading to the right. Best for wide data structures and when you have more horizontal screen space.

Vertical Layout

Displays the graph from top to bottom, with parent nodes at the top and children below. Ideal for deep hierarchical structures and when you prefer a tree-like visualization.

Frequently Asked Questions

How do I navigate large graphs?

Use the zoom controls in the top-right corner to zoom in/out, and click and drag anywhere on the graph to pan around. The reset button returns to the default view.

What happens when I click on nodes?

Clicking on nodes shows information about the node including its path in the JSON structure, data type, and nesting level. This helps you understand the data hierarchy.

Can I visualize very large JSON files?

Yes, but very large JSON files may take longer to render and might affect performance. Consider using fullscreen mode for better visualization of complex data structures.

Which layout should I choose?

Choose horizontal layout for wide, shallow data structures, and vertical layout for deep, hierarchical data. You can switch between layouts anytime to find the best view.
