Transform Your Data with Simple Function Nodes

This n8n workflow showcases the fundamental power of JavaScript within the platform to manipulate data. It begins with a 'Mock Data' node, which generates a simple array of strings. This initial output is then fed into a 'Function' node. Inside this node, a JavaScript map function iterates through the incoming data, wrapping each individual item into a new JSON object with a 'data' key. This process is ideal for restructuring data on the fly, preparing it for subsequent steps in your automation, or for testing purposes. It highlights how n8n allows for custom logic to be integrated seamlessly into your workflows.
