title: How to automate converting Excel xls files to Excel xml format?
body: <p>I have about 200 Excel files that are in standard Excel 2003 format. </p>
  
  <p>I need them all to be saved as Excel xml - basically the same as opening each file and choosing <strong>Save As...</strong> and then choosing <strong>Save as type:</strong> <em>XML Spreadsheet</em></p>
  
  <p>Would you know any simple way of automating that task?</p>
