how to replace value with constant value in json jolt?

Solution 1:

You can remove those attributes("geoLocation" and "currentCondition") by a remove transformation, then use # notation along with a shift transformation such as

[
  {
    "operation": "remove",
    "spec": {
      "geoLocation": "",
      "currentCondition": ""
    }
  },
  {
    "operation": "shift",
    "spec": {
      "*": "&",
      "#Snow": "currentCondition"
    }
  }
]
