Format cells before export excel in jquery datatable

I have implemented jquery datatable in my application.
But the problem is when I export the excel from datatable , then by default the type of all columns is text/General.
Is there any option to change the format of the column from string to date (MM/dd/YYYY) before export the excel?
This is our client requirement and I am not able to do that .
Please help me to resolve this .

Below are my sample code.

$(document).ready(function () {
            $.fn.dataTable.moment('D/MM/YYYY');
            $('#assetleakage').on('init.dt', function () {
                $("#assetleakage").wrap("<div class='table-wraper'></div>");
            }).dataTable({
                "columnDefs": [
                {
                    targets: [16, 17],
                    orderable: false
                },
                {
                    targets: [0, 1, 2, 3, 4, 9, 14],
                    searchable: false
                }],
                dom: 'lBfrtip',
                buttons: [
                    {
                        extend: 'csv',
                        exportOptions: {
                            columns: [6, 7, 8, 9, 2, 11, 12, 13, 14, 3, 5, 16]
                        }
                    },
                    {
                        extend: 'excel',
                        exportOptions: {
                            columns: [6, 7, 8, 9, 2, 11, 12, 13, 14, 3, 5, 16]
                        }
                    },
                    {
                        extend: 'pdf',
                        pageSize: 'A2',
                        exportOptions: {
                            columns: [6, 7, 8, 9, 2, 11, 12, 13, 14, 3, 5, 16]
                        }
                    }],
                "language": {
                    "lengthMenu": "Display records per page _MENU_",
                    "zeroRecords": "No records available",
                    "infoEmpty": "No records available",
                    "infoFiltered": "(filtered from _MAX_ total records)"
                }
            });
        });

Thanks in advance.
