How the Code Node Works

The Code node serves as your flexible programming environment within n8n:

• Write JavaScript or Python code directly in the workflow editor
• Access incoming data with simple syntax (e.g., items[0].json.name)
• Transform, manipulate, and enhance data with full programming capabilities
• Leverage libraries and functions to extend functionality
• Debug and test your code in real-time within the workflow

Unlike external development that requires deployment and maintenance overhead, the Code node keeps your custom logic directly within your workflow, maintaining visibility and manageability while providing unlimited extensibility.
