<b>Update 2: </b> Renamed to avoid conflict with existing csv2xls.pl,
and added Todos re [jmcnamara]'s feedback [73091|below].
Hmmm... this started out as a true [Snippet], but I wonder if it should be moved to [Code Catacombs]?
<p>
<b>Update 1: </b> And if I'd looked just a wee bit further than the pod, I'd have found <tt>/usr/local/lib/site_perl/Spreadsheet/WriteExcel/examples/csv2xls.pl</tt> which does this exact same thing. Hmmm... I wasn't reinventing a wheel, I was um, learning - yeah, that's it, I was learning! ;^D

=head1 Updated
2001-04-17 10:45 Renamed as text2xls - avoid conflict with existing csv2xls.
Tweaked todos re feedback from jmcnamara (S::WE author).
2001-04-16 Initial working code & posted to PerlMonks
=head1 Todos
Use Text::xSV by tilly or Text::CSV_XS for parsing text infile
Review and fix "prettify row header" which somewhat works, but not quite right.
Support for "freeze pane" anticipated in future S::WE
Test with different delimiters.
Use Pod::Usage to instead of &USAGE(). But appears to only be in Perl 5.6+ 8^(
Use @headerparms and foreach loop in headers section to reduce duplication.
Accept multiple infiles.
Save as "file.xls" (provided infile is "file") with -r switch.
Add support for "page delimiter" character for multiple worksheets.
Add support for $VERSION.
