An alternative approach you could try is to use a professional toolkit like LEADTOOLS which has document conversion classes that you can use with ASPX to convert the HTML to and XLS Excel File:
https://www.leadtools.com/sdk/document/document-converter

The toolkit includes a JavaScript Document Converter Control that you can use:

var url = "link to html file";
lt.Documents.DocumentFactory.loadFromUri(url, null)
.done(function (document) {
var jobData = new lt.Documents.DocumentConverterJobData();
jobData.documentFormat = lt.Documents.Writers.DocumentFormat.Xls;
jobData.rasterImageFormat = lt.Documents.RasterImageFormat. Unknown;
document.convert(jobData)
.done(function (result) {
var resultDocument = result.document != null ? result.document.url : result.archive.url;
window.open(resultDocument);
})
.fail(function (jqXHR, statusText, errorThrown) {
alert("Error converting document " + errorThrown);
});
})
.fail(function (jqXHR, statusText, errorThrown) {
alert("Error loading document " + errorThrown);
});

Hi,
Did you try to use Jquery setTimeout function? (when clicking download button)

function fnExcelReport()
{
var tab_text="";
var textRange; var j=0;
tab = document.getElementById('headerTable'); // id of table
for(j = 0 ; j < tab.rows.length ; j++)
{
tab_text=tab_text+tab.rows[j].innerHTML+"
";
//tab_text=tab_text+"";
}
tab_text=tab_text+"
";
tab_text= tab_text.replace(/]*>|<\/A>/g, "");//remove if u want links in your table
tab_text= tab_text.replace(/]*>/gi,""); // remove if u want images in your table
tab_text= tab_text.replace(/]*>|<\/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
{
txtArea1.document.open("txt/html","replace");
txtArea1.document.write(tab_text);
txtArea1.document.close();
txtArea1.focus();
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);
}

Try like this. Hope you will get. Thanks in advance
