## Example

We have a customers data in which we want to convert the *Address* information into proper case.

![beforeFx](https://github.com/astera-software/Astera_Data_Stack_v9/blob/main/.gitbook/assets/beforeFx.png)

We will map the *Address* data field to the *str* under the *Input* node inside the function transformation object.

You can see that the data inside the *Address* field has been converted to proper case.
