n8n provides built-in methods and variables for working with data and accessing n8n data. This section provides a reference of available methods and variables for use in expressions, with a short description.

Availability in the expressions editor and the Code node

Some methods and variables aren't available in the Code node. These aren't in the documentation.

All data transformation functions are only available in the expressions editor.
