Rendered XML
 

I need to dynamically generate an Excel spreadsheet for a client who
currently uses Excel to track time for her staff. As a test, I saved
her Excel spreadsheet as an "XML Spreadsheet" in Excel 2003. It created
a text file filled with XML code, which I can partially comprehend.

When I opened this file in Internet Explorer, it displayed exactly the
same as it does in Excel, down to the Menu bar. However, when my client
tries to open the same file on her computer, tha actual XML code is
displayed instead.

I am assuming that she needs to install an ActiveX control or some
other component to tell her copy of IE to render this XML file as an
Excel spreadsheet, but my searches on Google have not been specific
enough to find an answer -- perhaps I am not wording my query
correctly.

Anyways, if anyone can point me to a solution for my client I would be
much obliged. Thanks in advance.
