# Uppercase

> Convert every letter in a string to uppercase.

The **Uppercase** action converts text with JavaScript's standard uppercase
rules. Non-letter characters remain unchanged.

## Inputs

| Input    | Type   | Required | Description          |
| -------- | ------ | -------- | -------------------- |
| **Text** | String | Yes      | The text to convert. |

## Outputs

| Output   | Type   | Description                            |
| -------- | ------ | -------------------------------------- |
| **TEXT** | String | The input text converted to uppercase. |

For example, `Invoice #a19` becomes `INVOICE #A19`.
