title: Auto update data in google spreadsheet when data in Json url changed by Apps Script
body: <p>I am using " ImportJSON by Trevor Lohrbeer (@FastFedora)<a href="http://blog.fastfedora.com/projects/import-json" rel="nofollow">for ref.</a> " library for importing JSON feeds into Google spreadsheets.</p>
  
  <p>Simply to say I just input the function =ImportJSON(url, query, options) into the cell and the cell returns the data there.</p>
  
  <p>And everything is fine but the data in google spreadsheet would not be updated automatically when the JSON data in the url changed. I have to re-enter the function again into the cell or refresh the script manually to get it done.</p>
  
  <p>So can anyone suggest some solution to me?</p>
