How can I make a number as text

pantho2k2

I'm trying to make a number as text in datatables.js. If I do it manually in the excel file it works.. but when I do that programmatically it doesn't.. where I'm doing wrong.

    {
            "data": "ProductCode", "title": 'Product Code', "visible": true, responsivePriority: 1, render: function (data, type, row) {

                if (type === 'export') {

                    return "'" + data;
                }
                else {

                    return data;
                }
            }
        },

This is my button declaration

// Initialize Download Button
new $.fn.dataTable.Buttons(table, {

    buttons: [{
        extend: 'excel', text: 'Download Excel', className: 'btn-sm btn-success downloadButton', exportOptions: {
            columns: [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14],
            orthogonal: 'export'
        }
    }]
});
