oReq.responseType = "arraybuffer";

oReq.onload = function(e) {
  var arraybuffer = oReq.response;

  /* convert data to binary string */
  var data = new Uint8Array(arraybuffer);
  var arr = new Array();
  for(var i = 0; i != data.length; ++i) arr[i] = String.fromCharCode(data[i]);
  var bstr = arr.join("");

  /* Call XLSX */
  var workbook = XLSX.read(bstr, {type:"binary"});

  /* DO SOMETHING WITH workbook HERE */
  var first_sheet_name = workbook.SheetNames[0];
  /* Get worksheet */
  var worksheet = workbook.Sheets[first_sheet_name];
  console.log(XLSX.utils.sheet_to_json(worksheet,{raw:true}));
