A JSON tree viewer transforms flat JSON text into an interactive, collapsible hierarchy. Each object and array becomes a node you can expand or collapse, making it easy to navigate deeply nested data structures without scrolling through thousands of lines.
Paste your JSON and click Tree View to see the visual structure. Click ▶ to expand nodes, use Expand All / Collapse All to toggle the entire tree. String values are shown in green, numbers in orange, booleans in purple, and null in red for quick type identification.
Formatting adds indentation for readability. Tree view adds interactive expand/collapse controls and color-coded data types, making it much easier to explore large, nested JSON structures.
The tree view is read-only for exploring structure. To edit, copy the formatted output or switch to our JSON Formatter tool.
