Visual JSON Tree Editor

Instantly convert raw JSON into an interactive tree structure. This view is perfect for understanding the hierarchy of complex, nested API responses without getting lost in brackets and commas.

  • Expand/Collapse: Click folders to drill down into objects.
  • Copy Paths: Hover over any item to copy its dot-notation path (e.g., users[0].address.city).
  • Structure Check: Quickly verify if your arrays and objects are nested correctly.

Powerful Code Editor

For developers who prefer control, the code view offers a robust editing experience with syntax highlighting and real-time error detection.

Pro Tip:

You can drag the middle bar (in future updates) or use the "Split" toggle to customize your workspace. For files larger than 10MB, we recommend using the "Code Only" view for best performance.
