I am reading a json file from remote url and displaying it in DataTable.

<script>
    $(document).ready(function () {
        $('#example').DataTable(
            {
            ajax: {
                method: 'GET',
                url: 'https://chainformed.s3.us-east-1.amazonaws.com/Data/mostwatched.json',
                dataSrc: ''
            },
            paging: false,
            responsive: true,
            language: {
    url: "//cdn.datatables.net/plug-ins/1.12.1/i18n/tr.json",
  },

            columns: [
                { "data": "id" },
                { "data": "rank" },
                { "data": "name" },
                { "data": "watchlist" },
                { "data": "percentage" },
                { "data": "difference" },
                { "data": "timestamp" }
                
            ]
        });
        $('.dataTables_length').addClass('bs-select');
    });
</script>

I would like to be able to format and manipulate the data returned from that json file. What is the best way to do it?

For example, i would like to change the values from ({ "data": "watchlist" }) field to number format with comma. How can i achieve it?

I tried this but with no luck: https://datatables.net/reference/option/ajax.dataSrc
