convert specific properties of object to an array of objects

This is my original Object:

Data = {
  aesthetic: {
    heritage: 'aesthetic',
    description: 'sdokjosk',
    value: 5
  },
  architectural: {
    heritage: 'architectural',
    description: 'doodsjdj',
    value: 1
  },
  historical: {
    heritage: 'historical',
    description: 'dcnsdlnckdjsncksdjbk kjdsbcjisdc hsdk chjsd cjhds ',
    value: 4
  },
  score: 3
};

i want to write a function that goes through the object and converts the properties only with 'heritage' 'description' and 'value' into an array that would look like this: 

 [{
    "heritage": "aesthetic",
    "description": "sdokjosk",
    "value": 5
 },
  {
    "heritage": "architectural",
    "description": "doodsjdj",
    "value": 1
  },
  {
    "heritage": "historical",
    "description": "dcnsdlnckdjsncksdjbk kjdsbcjisdc hsdk chjsd cjhds ",
    "value": 4
  }
]

This is what I have tried:

Object.values(Data) but this returns an array with the 3 from the score property at the end

If you want to check all the keys you mentioned should present you can go with this :

Object.values(Data).filter(function(data){return data["heritage"] && data["description"] && data["value"]})

You can use Object.values() method to get the array of values, then filter only objects from it using Array#filter() method.

This is how should be your code:

var result = Object.values(Data).filter(x => typeof x == 'object');

Demo:

This is a working demo snippet:

var Data = {
  aesthetic: {
    heritage: 'aesthetic',
    description: 'sdokjosk',
    value: 5
  },
  architectural: {
    heritage: 'architectural',
    description: 'doodsjdj',
    value: 1
  },
  historical: {
    heritage: 'historical',
    description: 'dcnsdlnckdjsncksdjbk kjdsbcjisdc hsdk chjsd cjhds ',
    value: 4
  },
  score: 3
};

var result = Object.values(Data).filter(x => typeof x == 'object');
console.log(result);
