I have an excel file with multiple sheets, i uploaded it to my system and should trigger the sharepoint upload.

The excel file was uploaded to sharepoint but when I open the sharepoint an error pops out:

This is how i converted excel file to Binary:

var file = document.getElementById("myFile").files[0];
var reader = new FileReader(); 
reader.onload = function(ev) { 
var array = ev.target.result;
var fileByteArray = [];
for (var i = 0; i < array.length; i++) {
	fileByteArray.push(array[i]); 
}
