Can preview a XLSX or XLS in browser?

I have a MVC ActionResult controller that download the file.

If is PDF then using this JS code

var $obj = $('<object>');
$obj.attr("type", "application/pdf");
$obj.attr("data", myurl);                            
$("#id").append($obj);

Then i can preview the PDF in my app.

I want something similar for XLSX or XLS files.

If i hit the url i get the file but i cannot display it.

I tried with

<iframe src="https://docs.google.com/gview?url=myurl"></iframe>

but doesnt work.

Any ideas?
