JSON Viewer

# JSON Viewer

`utility.log_viewer`

Displays incoming payload as a collapsible JSON tree directly on the canvas. See the full structure of your data as it flows through the workflow.

Icon: `terminal`

## Ports

### Inlets

Input (any)

### Outlets

Output (any) — passthrough

## Configuration

No configuration fields. The JSON viewer automatically renders the incoming payload.

## Output

Passthrough — the incoming payload is forwarded unchanged to downstream nodes.

## Use Case

The JSON Viewer renders live on the canvas during execution, showing the full payload structure as a collapsible tree. Insert it between any two nodes to see exactly what data is being passed. Great for debugging data flow and understanding payload shape without needing to open the execution timeline.
