I am having trouble running your code.
I installed Excel::Writer::XLSX on my Win10 machine.

In the following code, new( 'filename.xlsx' ) succeeds and generates a workbook, but for some reason new ('C:/Details.xlsx' ); fails. I am not sure why that is? 

use strict;
use warnings;
use Excel::Writer::XLSX;
$|=1;


## Create Excel File.

#my $workbook = Excel::Writer::XLSX->new( 'C:/Details.xlsx' );
my $workbook  = Excel::Writer::XLSX->new( 'filename.xlsx' );
print "workbook is $workbook\n";

__END__

Update:
It is hard for me to imagine a spreadsheet with 616,337 rows! In theory, I guess this is possible, but not a good way to proceed.
