About JSON Graph Visualizer

The JSON Graph Visualizer is a tool for visually representing the structure of JSON data. Paste JSON into the text area and it is instantly displayed as a collapsible tree view.

Strings are green, numbers are blue, booleans are purple, null is gray, objects are orange, and arrays are teal, allowing you to identify data types at a glance. Statistics such as total node count, maximum depth, and occurrence counts for each data type are also displayed, enabling quick comprehension of the overall JSON structure.

All processing is done entirely in the browser, so sensitive data can be handled safely. Hover over any key to reveal a copy button that lets you instantly copy the JSON path to your clipboard. Use the search feature to filter by key name and quickly find specific sections within large JSON structures.
