I received a bytearray response from my API that was converted from a .xlsx file. I now need to open or download this bytearray in the browser after converting it back to its original file extension. Can anyone provide guidance on how to achieve this? I would greatly appreciate any help as I am unsure of what to do next.
One way to access data on the client side is by using readAsArrayBuffer. For more information, you can check out the documentation on Mozilla's website here.

});
var fileURL = URL.createObjectURL(file);
$window.open(fileURL);
