# Reshape

## `core.transform.reshape`

Define the exact scalar, object, or list output you want from workflow data.

<Tip>
  `core.transform.reshape` evaluates expressions anywhere in the input
  value. Use it to extract fields, rename keys, hardcode values, and
  compose new objects or lists from trigger data and earlier actions.
</Tip>

### Inputs

<ParamField path="value" type="any | array[any] | object" required>
  The value to reshape
</ParamField>

### Examples

**Return one value**

```yaml theme={null}
- ref: extract_owner_email
  action: core.transform.reshape
  args:
    value: ${{ ACTIONS.get_alert.result.data.owner.email }}
```

**Build a new object or list**

```yaml theme={null}
- ref: build_summary
  action: core.transform.reshape
  args:
    value:
      alert_id: ${{ TRIGGER.alert_id }}
      severity: ${{ TRIGGER.severity }}
      owner: ${{ TRIGGER.owner.email }}
      labels:
        - triage
        - security
```

**Use expressions and functions inline**

```yaml theme={null}
- ref: normalize_alert
  action: core.transform.reshape
  args:
    value:
      id: ${{ TRIGGER.alert_id }}
      title: ${{ TRIGGER.title || "Untitled alert" }}
      severity: ${{ FN.lowercase(TRIGGER.severity) }}
      source_ip_version: ${{ FN.check_ip_version(TRIGGER.source_ip) }}
      created_at: ${{ FN.to_isoformat(TRIGGER.created_at) }}
```
