Json change key to value

Question

I'm looking for a way in javascript to transform this json to something else.

{ 
  "John Doe": {
     "place": "Amsterdam"
  },
  "Jane Doe": {
     "place": "Paris"
  }
}

To something like this:

{ 
  { "id": 0,
    "name": "John Doe",
    "place": "Amsterdam"
  },
  { "id": 1,
    "name": "Jane Doe",
    "place": "Paris"
  },
}

How can I achieve this with javascript?

Answer 1

You can use Object.entries to get key/value pair and use map method to transform the object into the new one.

const data = { 
  "John Doe": {
     "place": "Amsterdam"
  },
  "Jane Doe": {
     "place": "Paris"
  }
}


const result = Object.entries(data).map(([key, value], index) => ({
  id: index,
  name: key,
  place: value.place
}))

console.log(result)
