I went through cpan page of (Excel::Writer::XLSX)
It only say one method which is open document, and all the sheets will be read into
an array, then you loop array to do some thing with sheets.
In my case I only have one sheet, I did datadump on object
my $workbook = Excel::Writer::XLSX->new( 'B.xlsx' ) ;
print Dumper $workbook;
but did not get any thing I could use.
So how do address one sheet with out looping into array.
