## Example

Suppose you want to **convert** all the characters of a series of strings in your input data **to uppercase**:

1. In your Pipeline, open the required [Action](https://docs.onum.com/the-workspace/pipelines/actions) configuration and select the input **Field**.
2. In the **Operation** field, choose **To upper case**.
3. Give your **Output field** a name and click **Save**. The characters in your input strings will be converted to uppercase.

For example:

{% code overflow="wrap" %}

```
Hello World! -> HELLO WORLD!
```

{% endcode %}

{% hint style="info" %}
You can try out operations with specific values using the **Input** field above the operation. You can enter the value in the example above and check the result in the **Output** field.
{% endhint %}
