I used below code for that but its works only in Firefox.
It also not allow customize exported file name. It takes a random file name.

 var tableToExcel = (function () {
        var uri = 'data:application/vnd.ms-excel;base64,'
          , template = '<html xmlns:o="urn:schemas-microsoft-com:office:office" xmlns:x="urn:schemas-microsoft-com:office:excel" ><head><!--[if gte mso 9]><xml><x:ExcelWorkbook><x:ExcelWorksheets><x:ExcelWorksheet><x:Name>{worksheet}</x:Name><x:WorksheetOptions><x:DisplayGridlines/></x:WorksheetOptions></x:ExcelWorksheet></x:ExcelWorksheets></x:ExcelWorkbook></xml><![endif]--></head><body><table>{table}</table></body></html>'
          , base64 = function (s) { return window.btoa(unescape(encodeURIComponent(s))) }
          , format = function (s, c) { return s.replace(/{(\w+)}/g, function (m, p) { return c[p]; }) }
        return function (table, name, filename) {
            var OriginalHTML = $('#' + table + '').html();
            if (!table.nodeType) {

                table = document.getElementById(table);
            var ctx = { worksheet: name || 'Worksheet', table: table.innerHTML }

            //window.location.href = uri + base64(format(template, ctx))
            document.getElementById("aExportTable").href = uri + base64(format(template, ctx));
            document.getElementById("aExportTable").download = filename;
How to&Answers:

Try a blob. Should work in IE10+, Chrome/Safari and Fx

  window.URL = window.URL || window.webkitURL;
  var blob = new Blob([format(template, ctx)]); // format is part of OP's code
  var blobURL = window.URL.createObjectURL(blob);
  if (blobURL) {
      .attr("href", blobURL)
      .attr("download", fileName)
      .text("Download "+fileName+" for import")
  else {
    $("#downloadLink").html("Please cut and paste from the table below");


The following code worked perfect for me with IE8+, Chrome and Firefox!
It´s the easiest way to Export HTML tables to Excel without using a blob, ActiveX-Elements or downloadify:

Just insert an empty Iframe in your HTML document:

<iframe id="txtArea1" style="display:none"></iframe>

Add the following function to your Script section and replace the table id:

function fnExcelReport()
              var tab_text="<table border='2px'><tr bgcolor='#87AFC6'>";
              var textRange; var j=0;
              tab = document.getElementById('headerTable'); // id of table

              for(j = 0 ; j < tab.rows.length ; j++) 

              tab_text= tab_text.replace(/<A[^>]*>|<\/A>/g, "");//remove if u want links in your table
              tab_text= tab_text.replace(/<img[^>]*>/gi,""); // remove if u want images in your table
                          tab_text= tab_text.replace(/<input[^>]*>|<\/input>/gi, ""); // reomves input params

                   var ua = window.navigator.userAgent;
                  var msie = ua.indexOf("MSIE "); 

                     if (msie > 0 || !!navigator.userAgent.match(/Trident.*rv\:11\./))      // If Internet Explorer
                                sa=txtArea1.document.execCommand("SaveAs",true,"Say Thanks to Sumit.xls");
                      else                 //other browser not tested on IE 11
                          sa = window.open('data:application/vnd.ms-excel,' + encodeURIComponent(tab_text));  

                          return (sa);

and finally call the function:

<button id="btnExport" onclick="fnExcelReport();"> EXPORT </button>

or with JQuery:

$("#btnExport").click(function () {



The Firefox supports the HTML 5 feature data-uri here data:application

If you want to make it work across all browsers, better do it in server side and set the response ContentTypeaccordingly.
