DataTables and export to excel – number formating

$(document).ready(function () {
    $.fn.dataTable.moment(lang == "en" ? 'DD/MM/YYYY' : 'DD.MM.YYYY');
    categories_table = $('.datatable').DataTable({
        order: [[1, 'desc']],
        language: datatable_lang,
        dom: 'Bfrtip',
        buttons: [
            {
                extend: 'collection',
                autoClose: 'true',
                text: '<i class="download icon">',
                tag: 'span',
                buttons: ['csv', 'print', 'excel']
            }
        ]
    });
});

This gives nice looking format for price, like “8,00” as example. But when I export that to excel, I get “800” as value. And if number is “18,00”, excel will show it as “1,800”.

Is there any way to sort this out and have same values in excel as well?

Thanks
