Master Looping in n8n: A Beginner's Guide
detail.loadingPreview
Demystify iteration in n8n with this beginner-friendly workflow. Learn how n8n handles arrays by default and how to gain precise control over your loops using the 'Loop Over Items' node for efficient batch processing.
About This Workflow
This n8n workflow template is designed for newcomers to automation, providing a clear understanding of how n8n handles iterative processes. It contrasts the default behavior of nodes processing entire arrays as single items with the explicit control offered by the 'Loop Over Items' node. By demonstrating the difference between an unsplit array of strings and a split array where each element is processed individually, users will grasp the fundamentals of controlled looping and batch processing. The workflow includes helpful sticky notes and readily executable setup instructions to make learning intuitive and practical.
Key Features
- Understand n8n's default array handling.
- Learn to use the 'Loop Over Items' node for custom iteration.
- Differentiate between processing an array as one item vs. individual items.
- Gain control over batch processing and sequential execution.
- Includes clear setup instructions and explanatory notes.
How To Use
- Import the Workflow: Load this JSON snippet into your n8n instance.
- Set Up Input Data: Double-click the 'Manual Trigger' node, click 'Edit Output,' paste the provided JSON payload, and save.
- Run the Workflow: Execute the workflow manually.
- Observe Results: Examine the output of the 'Result1' and 'Result2' nodes to see the difference in how arrays are handled with and without explicit looping.
- Experiment: Optionally remove the 'Wait Node' for faster execution or adapt the 'Split Out' node to process different array fields.
