**Transform categories**: Struct

## Declared arguments

* **Dataset:** Dataset containing struct column.<br>*Table*
* **Locators:** Locators for fields to access in the struct.<br>*List\<Tuple\<StructLocator, Literal\<String>>>*
* **Struct:** Input struct.<br>*Column\<Struct>*

## Examples

### Example 1: Base case

**Argument values:**

* **Dataset:** ri.foundry.main.dataset.a
* **Locators:** \[(airline.name, airline), (tail\_no, tail\_number)]
* **Struct:** `raw`

**Input:**

| raw |
| ----- |
| {<br> **airline**: {<br> **id**: NA,<br> **name**: new air,<br>},<br> **tail\_no**: NA-123,<br>} |
| {<br> **airline**: {<br> **id**: FA,<br> **name**: foundry airways,<br>},<br> **tail\_no**: FA-123,<br>} |

**Output:**

| airline | tail\_number |
| ----- | ----- |
| new air | NA-123 |
| foundry airways | FA-123 |
