best Excel module

A couple of years ago, I converted our database output from wide
formfeed paper printed on obselete line printers and delivered
manually to printing them as PDF files delievered electronically. I am
now converting our database output into CSV or XML files that can be
opened with Excel, which is the user desiderata. Some of these files
have hundreds of records, and PDF files can't be sorted or filtered,
although they are a lot better than the old line printed variety.

However, I am getting user complaints that the Excel files are ugly,
without all the nice formatting that Excel supports. I have just
looked at CPAN and discovered 149 modules for use with Excel, and see
several that might do what I need, such as Spread***::WriteExcel,
Querylet::Output::Excel::OLE, Querylet::Output::Excel::XLS,
Spread***::SimpleExcel, etc.

Are there maybe two or three that I can test that focus on cosmetics?
I need something that can create colored backgrounds with bolded text,
etc.

Thanks, CC.
