2. In the **Operation** field, choose **String to list**.
3. Set **Separator** to `/`.
4. Give your **Output field** a name and click **Save**. The values in your input field will be transformed into a comma-separated list. For example:

<pre><code><strong>hello/my/world -> hello,my,world
</strong></code></pre>

{% 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 %}
