# About Transformers (Deprecated)

> For the full documentation index, see: https://docs.mulesoft.com/llms.txt

Transformers, such as Object to XML and Object to String, are deprecated data transformation
components that are distinct from the Transform component.

In this release, you should use DataWeave expressions in the Transform component to perform data
transformations instead of relying the deprecated components.

Note that transformers are only available through the Compatibility module (available starting in
Mule version 4.1).
