About JSON Viewer

Paste any JSON document to explore it as an interactive, collapsible tree — expand and collapse objects and arrays, and see types color-coded at a glance.

The viewer validates your JSON as you type and reports errors with line and column numbers. Everything runs locally in your browser.
