Transform data

n8n gives you several ways to modify, restructure, or enrich data as it moves through your workflow.

In this section

• Approaches for transforming data: compare transformation nodes, expressions, the Code node, and the AI Transform node.

• Expressions for data transformation: use expression transformation functions anywhere expressions are supported.

• Expression reference: reference for every built-in method and variable available in expressions.
