I hope that I understood your question correctly..

The following Code will edit every "Date" element and convert it.

var arr = [
    {
        "id": 2,
        "Date": "2021-12-16T13:55:00.000Z"
    },
    {
        "id": 9,
        "Date": "2021-12-16T13:55:00.000Z"
    },
    {
        "id": 14,
        "Date": "2021-12-16T13:55:00.000Z"
    }
];

arr.forEach((element, index) => {

    var date = new Date(element.Date)

    var newdate = date.toISOString().slice(0, 10)   " "   date.toTimeString().slice(0,5)   " "   (date.getHours() >= 12 ? "PM" : "AM");

    arr[index].Date = newdate;


});

console.log(arr);

You can do it like so:

const data = [{
        id: 2,
        Date: '2021-12-16T13:55:00.000Z'
    },
    {
        id: 9,
        Date: '2021-12-16T13:55:00.000Z'
    },
    {
        id: 14,
        Date: '2021-12-16T13:55:00.000Z'
    }
];

const newData = data.map((el => ({
    ...el,
    Date: (new Date(Date.parse(el.Date))).toLocaleString('en-US')
})));

console.log(newData);
