Send Self-Destructing messages in Google Docs

Google Docs also provides you the facility to send Self-Destructing messages.  The code that works behind the scenes is shown as under.

function onOpen() {

 

 var time = 10; // Wait Time (in seconds)

 

 var ss = SpreadsheetApp.getActiveSpreadsheet(); 

 ss.toast("This message will disappear after " + time + " seconds");

 

 Utilities.sleep(time*1000); 

 ss.toast("We are now sending this private note to the shredder");

 ss.getActiveSheet()

   .getRange(1, 1, ss.getLastRow(), ss.getLastColumn()).clear(); 

}

This script is known as Google Apps Script.  Here we simply attach an open trigger to the Google Sheet that becomes active as soon as the message is opened.  It waits for 10 seconds and runs the clear function to clear the entire message to make all the cells empty and whole message gets vanished.
