      {storeId: '2548240'},
      {storeId: '9566666'}
    ],

Answer 1

You can't have a multiple storeId key in an objet. But you can have multiple object with storeId.

overSerializedItems: [{storeId:...}, {storeId:...}]

You can transform like that:

var result = [
{
   "storeId": "4543",
   "type": "full",
   "overSerializedItems": [3548240,91511753,345555],
},
{
   "storeId": "5462",
   "type": "half",
   "overSerializedItems": [2548240,9566666],
}
];

 var trans = result.map(w => {
  return {
     storeId: w.storeId,
     type: w.type,
     overSerializedItems: w.overSerializedItems.map(x => { return {storeId: x.toString()} })
  }
})

Answer 2

You need to use two forEach() loop for that output:

 var result = [{ "storeId": "4543", "type": "full", "overSerializedItems": [3548240, 91511753, 345555], }, { "storeId": "5462", "type": "half", "overSerializedItems": [2548240, 9566666], } ]; result.forEach(function(obj){ obj.overSerializedItems.forEach(function(val, index){ obj.overSerializedItems[index] = {'store':val.toString()}; }); }); console.log(result);
