title: How do you retrieve data from a Google Docs Spreadsheet?
body: <p>I found this wonderful example of pulling data from a Google spreadsheet in JSON:
  <a href="http://code.google.com/apis/gdata/samples/spreadsheet_sample.html" rel="nofollow">http://code.google.com/apis/gdata/samples/spreadsheet_sample.html</a></p>
  
  <p>However, I can't seem to get it to work for a spreadsheet I created. I've made the doc public and published it, and tried every possible tweak on the key and sheet "name". Has anyone successfully used this? I've seen the Zend GData library, but would rather use JSON.</p>
  
  <p>Thanks in advance for any tips.</p>
