JSON Node

The JSON Node lets you inspect, visualize, and pass through JSON data.

See, copy, and forward JSON from any previous node in your workflow.

Purpose

Debugging: Inspect the structure and content of flowing data.
Visualization: Human-readable view of complex JSON objects/arrays.
Data Passthrough: Examine data without modifying it for the next node.
Verification: Confirm that outputs are valid JSON.

Configuration

Property	Type	Description	Default
`label`	string	Descriptive name for the node instance.	`JSON Output`

Input Data

The node's main value, inputData, is dynamically populated by data flowing in—no manual config needed.

Inputs and Outputs

Input (Left Handle):
Receives data from any upstream node. Intended for JSON, but will try to process any value.

Output (Right Handle):
Emits the exact same data (inputData) that it received, so you can inspect without interrupting the flow.

Visualization and Functionalities

Data Display: Shows formatted JSON using JSON.stringify(data, null, 2) inside a scrollable <pre>.
If no data: shows No data received.
If un-stringifiable: shows [Invalid JSON].
Copy JSON: "Copy JSON" button puts formatted JSON in clipboard. Shows "Copied!" for confirmation.
Status Indicators: Visual feedback for success or errors, based on results.

Example: Inspecting API Response

Suppose you have an HTTP Request Node fetching API data and want to inspect the JSON response before using it.

Configure an HTTP Request Node to call an API endpoint that returns JSON.
Connect the Output of the HTTP Request Node to the Input of a JSON Node.
Set the label of the JSON Node to API Response Inspector.

When the flow runs, the JSON Node displays the formatted response. You can easily view or copy the structure, and the data is also passed to downstream nodes.

While the node attempts to display any data, its features are optimized for valid JSON only.

The JSON Node is your go-to tool for diagnosing, viewing, and forwarding JSON in any data flow.
