Convert Excel .xls to .csv, .xml or JSON in Javascript <p>Using <code>Javascript</code>, specifically <code>Google Apps Script</code> (GAS), I need to convert an <code>.xls</code> file to <code>JSON</code>; but I would settle for <code>.csv</code> or <code>.xml</code>.</p> <p>Does anyone know any way to do this? Some library, perhaps? Or a private script willing to share? (Note: GAS can not recognize <code>ActiveXObject</code>)</p> <h3>Prior research (does not apply)</h3> <p><a href="http://stackoverflow.com/questions/662859/converting-csv-xls-to-json">This</a> question does not apply because I am asking for a solution coded in Javascript (or a workaround for Google Apps Script). (The answers to the above question focus on a Java solution and other various .csv to JSON converters.)</p> <p>Yes, I know there is an open <a href="https://code.google.com/p/google-apps-script-issues/issues/detail?id=1019" rel="nofollow">issue</a> for GAS already in the works. But I was wondering if anyone has coded any .js workaround to do the job in the meantime?</p>
