Some of my datatable column shows as number datatype in excel how to prevent it defined as number without comma delimiter - excel

Question

I have 4 columns in datatables and wanted to export into xlsx file 2 of the column, one column is name and phone, but after export, one of the column (phone) will show millions as 1,000,000 for example. I wish that phone number column to be treated as text but failed many times
This is my code and loading the data from json text using php
$(document).ready(function()
{
$('#example').DataTable( {
"ajax": "json.php",
"pageLength": 100,
"deferRender": true,
dom: 'Bfrtip',
lengthMenu: [
[ 10, 25, 50, 100, 200, 500, 1000],
[ '10 rows', '25 rows', '50 rows', '100 rows', '200 rows' , '500 rows', '1000 rows']
],
buttons: ['pageLength','copy',
{extend: 'excelHtml5',
filename: 'export',
title: null,
exportOptions: {
columns: [ 1, 2 ],
format: {
body: function (data, row, column, node )
{
return column === 2 ? "\0" + data : data;
//return column === 2 ? = & "" + data : data;
}
},
}
}
],
} );
} );
