# Set Data

> Construct a structured object. Exact configuration, ports, placement, and execution behavior.

**Node type:** `set_data` · **Version:** `1` · **Category:** Data

Construct a structured object. This node does not declare an external side effect.

## Configuration

| Field    | Type   | Default           | What it controls                             |
| -------- | ------ | ----------------- | -------------------------------------------- |
| `values` | object | `{"key":"value"}` | Structured JSON object produced by the node. |

## Workflow JSON

The editor stores this node with the following implemented default configuration:

```json title="Default node configuration" theme={"system"}
{
  "type": "set_data",
  "version": 1,
  "configuration": {
    "values": {
      "key": "value"
    }
  }
}
```

Values may be entered literally or mapped from an earlier compatible output when the inspector exposes a mapping control. See [Variables and data mapping](/workflows/variables-and-data).

## Inputs

| Port     | Type     | Required | Description |
| -------- | -------- | -------- | ----------- |
| `values` | `object` | No       | Object      |

## Outputs

| Port    | Type     | Required | Description |
| ------- | -------- | -------- | ----------- |
| `value` | `object` | No       | Object      |

## Where it can run

* Desktop local runner
* Paired self-hosted runner
* Hosted runner

## Test and inspect

Use **Test node** in the editor to preview this step with the current configuration. A full run records resolved inputs, outputs, logs, duration, and any artifacts in the execution inspector. Side-effecting or destructive nodes can require an additional confirmation or approved workflow permission.
