@FM916 I think so. I was using this code until today, when I have noticed that code isn't working anymore. When i put the example link on webbrowser:

https://spreadsheets.google.com/feeds/cells/1hbHqrnYa4oMUquZcq8WkTJk0kI0t9scGBwro-EH-ALA/1/public/values?alt=json-in-script&callback=doData
returns this:Not the json data anymore! :(
