Split Single Item's JSON Array into Multiple n8n Items

Effortlessly transform nested JSON arrays into individual n8n items using Functions, boosting automation speed and simplifying data processing.

Manual Trigger

This workflow demonstrates how to transform a single n8n item that contains an array of JSON objects into multiple individual n8n items. The initial 'Mock Data' Function node simulates a common scenario where a preceding node might output data in a nested format, such as a list of records within one primary item. The subsequent 'Create JSON-items' Function node then processes this nested structure. It iterates through the array of JSON objects found within the 'json' property of the first incoming item. For each object in that array, it generates a new, separate n8n item, with the individual JSON object assigned to the 'json' property of the new item. This process effectively 'flattens' or 'unnests' the data, making each record accessible as an independent n8n item, which is often required for subsequent processing by other n8n nodes. This pattern is useful when an API or data source returns a collection of data as a single payload, and you need to process each element of that collection independently.
