JSON Tree Viewer is a free online tool that transforms JSON data into an interactive, collapsible tree structure. Click on objects and arrays to expand or collapse them. Great for exploring deeply nested API responses, config files, and datasets.

  2. Explore the tree — click arrows to expand/collapse nodes.
  3. Values are color-coded by type: strings, numbers, booleans, null.
  4. Click Sample to load example data.
