define, like
constant, is used at compile-time; hence, it has to be declared before any run. In this case, it really doesn't need to be used, but I used it to for debugging. The result
might surprise you.
#!/usr/bin/perl
use Modern::Perl '2012';

my $parser = Spreadsheet::ParseExcel->new();
my $workbook = $parser->parse('tags sample.xls');
my $page = $workbook->{Worksheet}[0];
my ( $tags, $pages, $pviews, $pvisits );
format STDOUT_TOP =

format STDOUT =

foreach ( my $i = 0 ; $i{'MaxRow'} ; ++$i ) {
$tags = cell( $page, $i, 0 );
$pages = cell( $page, $i, 1 );
$pviews = cell( $page, $i, 2 );
$pvisits = cell( $page, $i, 3 );

return $val;
}
return '';
