Restructure JSON Array Elements into Individual Items

Function

Manual Trigger

This n8n workflow demonstrates how to restructure data, specifically by transforming an array of strings contained within a single JSON item into multiple individual JSON items. The process begins with a 'Mock Data' Function node that generates a sample input: a single item whose `json` property holds an array of strings like `["item-1", "item-2", ...]`. The subsequent 'Function' node then processes this input. It iterates through each string in the input array. For every string, it creates a new, separate output item. Each new item's `json` property will contain an object with a `data` key, holding one of the original strings. This effectively "flattens" the array, making each original string available as an independent, structured data item for downstream processing in other n8n nodes. This pattern is useful when an API or previous node returns a consolidated array that needs to be broken down for individual operations.
