Export to excel that works from IE 8 to11 using Javascript with open, save, saveas dialog

Question

I would like to know if any one has inputs on how I can export a html table to excel on client side that works in IE 8 to IE 11.

I tried:

var blob = new Blob(table], { type: 'text/plain;charset=utf-8;' });   
window.navigator.msSaveOrOpenBlob(blob , 'Export.xls');

But, this works only in IE 11 as the Blob constructor is not supported in IE 8.

Also tried:

var sa = txtArea1.contentWindow.document.execCommand("SaveAs", true, "IE Excel Export.xls");

But this one doesn't show the Open, Save and Save as dialog.

Please suggest on any other option I can use.

Thanks in advance.
