title: How to run javascript byc clicking a cell in google sheets?
body: <p>Google sheets allows you to write scripts in javascript, the same way excel lets you write VBA to automate tasks.</p>
  
  <p>I'd like to make a cell in my google spreadsheet clickable, so that when it is clicked, my function will run.</p>
  
  <p>I've found that it's possible to create custom buttons by inserting a drawing, but I'd really like this to be any time a particular cell is clicked, rather than a button which can move around and looks awkward in the sheet.</p>
  
  <p>Is it possible?</p>
  
  <p>Thanks for any advice.</p>
