  Serial.println(line);
  if(line == "On\r"){
//  Serial.println("Led On");
  digitalWrite(2, HIGH);
  }
    if(line == "Off\r"){
//  Serial.println("Led Off");    
  digitalWrite(2, LOW);

  }

if (line == "\r") {
  if (disp){

Hello, sorry for the delay this version is a little old, in that case that required to activate a gpio, the quick solution was to edit directly in the library, perform tests with certain improvements, if you can see them and try: https://youtu.be/L68MxmHewww   and tell me, what are you doing ?, the creator of the library also made improvements. https://github.com/electronicsguy/ESP8266/tree/master/HTTPSRedirect

Hello, you need the data coming from google spreadsheets to return from the function in a string and to be able to use it from void main, correct. Give me some time to edit the library and try, ready. regards
