Re-parent a JSON object using Jolt

Question

I\'d like to move a JSON object down one level using Jolt. Here\'s my input data :

{
    \"rating\": {
        \"primary\": {
            \"value\": 3,
                


        

Answer 1

Spec

[
  {
    "operation": "shift",
    "spec": {
      "@": "NEWPARENT"
    }
  }
]

FYI, the "root" you are seeing is an artifact of the way that Jolt deals with the fact that the top level JSON input can be either a List or a Map, and that you want to be able to Transform a List into a Map (and vice versa).

So, jolt "wraps" the input so that it is "always" transforming a Map that has a single key "root", with a value that is the input.
