# To lower case

## Description

This operation converts all characters in a string or text to their lowercase equivalents. This transformation is often used to standardize text for tasks like case-insensitive comparisons, sorting, or data normalization.

***

## Data types

These are the input/output expected data types for this operation:

### Input data

![](/files/lPHCVhp93aYrWgLIlhNp) - Strings to be converted.

### Output data

![](/files/3itBmKrRqasWlG3dGBlS) - Strings where all uppercase letters (`A-Z`) have been converted to their lowercase counterparts (`a-z`). Characters that are already lowercase or are not alphabetic (e.g., numbers, symbols, whitespace) remain unchanged.

***

## Example

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

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

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 %}
