# Extend Data 360 by Using Custom Code with Code Extension

With code extension, you can bring your custom Python code into Data 360 to extend Data 360's native capabilities. If native Data 360 features don't meet your business requirements, deploy your custom logic across supported Data 360 features such as batch data transforms. For example, if you need advanced data transformations for your business use case, you can deploy custom business logic to Data 360 to implement your requirements. Salesforce CLI with the Code Extension plugin and the Data Custom Code Python SDK work together as your local toolchain for Code Extension.

**Where:** This change applies to Data 360 Enterprise, Performance, Developer, and Unlimited editions.

**When:** This feature is available for batch data transforms starting in May 2026. Not available in Government Cloud.

**How:** Install Salesforce CLI, the Code Extension plugin, and the Data Custom Code Python SDK on your machine. Write your code and deploy it to a sandbox. Validate your code by invoking custom code: Create a batch data transform and then run it. Finally, move your code to production by using a data kit for processing production data.
