title: Reading and writing Excel files using Ruby on a server without Excel installed
body: <p>I need to read and write (-> transform) Excel files on a Linux server, which of course does not have Excel installed. For Python there exists <a href="http://www.python-excel.org/">http://www.python-excel.org/</a>. Is there something similar for Ruby? Processing of the latest Office format is probably not required. Just old xls files should be enough.</p>
