Transform Your Data with n8n's Powerful Function Nodes
detail.loadingPreview
Leverage n8n's versatile Function nodes to effortlessly transform and manipulate your data. This workflow demonstrates how to create mock data and then process it using custom JavaScript, opening up a world of automation possibilities.
About This Workflow
This n8n workflow showcases the power of its Function nodes for advanced data manipulation. Starting with a 'Mock Data' node, we generate a simple array of strings. This data is then piped into a second 'Function' node, where custom JavaScript code transforms each item into a structured JSON object with a 'data' key. This capability allows you to perform complex data cleaning, enrichment, formatting, and custom logic within your workflows, making n8n an indispensable tool for any automation professional seeking granular control over their data pipelines.
Key Features
- Custom Data Generation: Create and inject your own test or initial data directly into workflows.
- JavaScript-Powered Transformation: Apply any JavaScript logic to reshape, filter, and reformat your data on the fly.
- Flexible Data Structuring: Easily convert simple data into complex JSON objects as per your requirements.
- Seamless Node Integration: Effortlessly connect and pass data between Function nodes and other n8n nodes.
How To Use
- Add 'Mock Data' Node: Drag and drop a Function node onto your canvas and rename it 'Mock Data'.
- Configure 'Mock Data': In the node's parameters, paste the JavaScript code
return [{json:["item-1", "item-2", "item-3", "item-4"]}];to create your initial data. - Add 'Function' Node: Add another Function node and rename it 'Function'.
- Connect Nodes: Draw a connection from the 'Mock Data' node to the 'Function' node.
- Configure 'Function' Node: Paste the JavaScript code
return items[0].json.map(item => { return { json: { data:item }, }; });into the 'Function Code' parameter. This code iterates through the incoming data and wraps each item in a new JSON object with a 'data' key. - Run Workflow: Execute the workflow to see your mock data transformed.
