Merge JSON objects

Merge multiple JSON objects into one. The merge is shallow: only top-level keys are combined, and when the same key appears in several inputs, the value from the later input wins.

Parameters

Key

Optional wrapper key. When set, the merged object is wrapped under this single key: the output becomes {"<key>": <merged object>} instead of the merged object itself.

Input

JSON Elementrequired

The JSON objects you want to merge. The connector is Unlimited: wire each upstream object to it. It also accepts an Array of objects or a JSON array — the array is flattened and its elements are merged one by one. Any element that is not an object fails the step.

Output

JSON Element

The merged JSON object (or, if "Key" is set, an object with the merged result nested under that key).
