Everything runs in your browser. Your data is never sent to our servers.

JSON Tree Viewer renders a JSON document as a collapsible tree, making it far easier to understand than raw text — especially for large, nested data.

Click a node to expand or collapse its branch. Value types (string, number, boolean, null) are color-coded for readability.

It is great for debugging API responses and understanding data structure. Everything runs in the browser; nothing is uploaded.

Is my data sent to a server?

No. JSON Tree Viewer runs entirely in your browser using client-side libraries. Your data never leaves your device.
