Javascript Question

Exporting table to Excel file using javascript

I was able to create the XLS file using JavaScript using Active X controls.

For IE I did the following :

var objExcel = new ActiveXObject("Excel.Application");
objExcel.visible = false;
var objWorkbook = objExcel.Workbooks.Add;
var objWorksheet = objWorkbook.Worksheets(1);
objExcel.visible = true;

But to use ActiveX controls I need to go to Internet Option -> Security ->Custom Level ->Enable Initialize and script ActiveX controls not marked as safe for scripting . After enabling this only I am able to create the XLS file.

Is there any other way to create the XLS file in IE-11 apart from active X
I tried to use the following

var vDiv = document.getElementById('dvData');
vDiv.innerHTML = vTable;
var url='data:application/,' + encodeURIComponent($('#dvData').html()) ;

but its not working in IE-11. I need to use pure javascript.

Thanks in advance

First you need to convert the table to a way that excel can understand it.
Expecting a html code to work out of the box in excel is wrong.

Once you got the data in the right format you should create a Blob and download that, one good lib to help out with saving blob is FileSaver.js

var chunk = '<?xml version="1.0"?>...'
var blob = new Blob([chunk], {type: 'application/'})
saveAs(blob, 'filename.xls') // using FileSaver.js
