How to export a report in .xls format

<p><font face="arial,helvetica,sans-serif" size="2">For my current project I have to take existing Crystal Report files and export them into Excel. I cannot use a .csv file, it has to be a .xls file in order to preserve the formatting. Does the Crystal plugin for Eclipse support this feature? I know it can export to .csv but how do I export to .xls? </font><font face="arial,helvetica,sans-serif" size="2">Thanks in Advance, </font><font face="Arial" size="2">Dave Amundsen</font></p>
