Data is the information that n8n nodes receive and process. For basic usage of n8n you don't need to understand data structures and manipulation. However, it becomes important if you want to:
- Create your own node
- Write custom expressions
- Use the Function or Function Item node
This section covers:
- Data structure
- Transforming data
- Process data using code
- Pinning and editing data during workflow development.
- Data mapping and Item linking: how data items link to each other.
