<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">

    <script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/2.2.4/jquery.min.js"></script>
    <script src="table2excel.js" type="text/javascript"></script>
    <script type="text/javascript">
        $(function () {
            $("#btnExporttoExcel").click(function () {
                $("#tblStudent").table2excel({
                    filename: "Your_File_Name.xls"
                });
            });
        });
    </script>
