Example

For the following JSON object from the API:

{
  "id": 1,
  "name": "Rick Sanchez",
  "status": "Alive",
  "species": "Human",
  "gender": "Male",
  "origin": {
    "name": "Earth (C-137)"
  },
  "locations": [
    {
      "name": "Earth (C-137)"
    },
    {
      "name": "Citadel of Ricks"
    }
  ]
}

mappings:
  - field: name # Rick Sanchez
    label: Name
  - field: status # Alive
    label: Status
  - field:
      origin: name # Earth (C-137)
    label: Origin
  - field:
      locations:
        1: name # Citadel of Ricks
    label: Location

    - value: 1
      to: Connected
    - any: true # will map all other values
      to: Unknown
- field: key5
  label: Power
  format: float
  scale: 0.001 # can be number or string e.g. 1/16
  suffix: kW
