Not sure if this is an actual problem, but it is an inconsistency in your logic:

...
my $xlsx = $fp =~ s\csv\xlsx\;
...
my $workbook  = Excel::Writer::XLSX->new("$fp");

[download]

Should this not actually be

...
my $xlsx = $fp;
$xlsx =~ s/csv/xlsx/;
...
my $workbook  = Excel::Writer::XLSX->new("$xlsx");

[download]

In the s/// they do need to be forward slashes, not backslashes, which have a different meaning.
