var input = document.getElementById("arquivo");
var output = document.getElementById("saidaTextArea");


input.addEventListener("change", function() {
  if (this.files && this.files[0]) {
    var myFile = this.files[0];
    var reader = new FileReader();

    reader.addEventListener('load', function(e) {
      output.textContent = e.target.result;
    });

    reader.readAsBinaryString(myFile);
  }
});
