title: Exporting data to iWork Numbers
body: <p>Has anyone tried exporting data to Numbers in iWork? I want to generate a spreadsheet programmatically but I'm not having much success.</p>
  
  <p>I've tried unzipping a .numbers document and analysing the XML to see if I could interpret it but it's far too complicated. Also, I couldn't find the DTDs used by Apple.</p>
  
  <p>Judging by what's <a href="http://www.tbray.org/ongoing/When/200x/2005/09/18/Apple-XML" rel="nofollow noreferrer">out</a> <a href="http://developer.apple.com/mac/library/documentation/AppleApplications/Conceptual/iWork2-0_XML/Chapter01/Introduction.html#//apple_ref/doc/uid/TP40002479-CH202-DontLinkElementID_62" rel="nofollow noreferrer">there</a> this is an almost impossible task. Does anyone have any ideas?</p>
