When I run the program shown here: 
#!C:\strawberry\perl\bin\perl.exe
use strict;
use warnings;
use Spreadsheet::ParseExcel;
use Spreadsheet::ParseExcel::SaveParser;

# Specify cell H2’s row and col
my $row = 1;
my $col = 7;
my $worksheet_num = 0;

# Create a parser that can read/write/display cells in an existing Exc
+el spreadsheet
my $parser   = Spreadsheet::ParseExcel::SaveParser->new();

if ($parser) {
  print "parser is defined\n";
} else {
  print "parser is NOT defined\n";
}

# Parse the ‘Build_Scheduler.xlsx’ spreadsheet
my $template = $parser->Parse('Build_Scheduler.xlsx');

if ($template) {
  print "template is defined\n";
} else {
  print "template is NOT defined\n";
}

# Specify leftmost tab (“0”) as the worksheet to be modified
my $worksheet = $template->worksheet(0) || die("$@$!");

# Overwrite the AsOf string value in tab = “Monday”, cell H2. (05/05/2
+016 2:00PM is replaced by 05/05/2016 2:00PM)
$worksheet->AddCell( $row, $col, '05/12/2016 2:00PM' );

I find the the call to my $template $parser->Parse('Build_Scheduler.xlsx') fails and returns "undefined", causing the later call my $worksheet = $template->worksheet(0) to fail. My Perl version is Strawberry 5.18.1001 Can someone let me know why my
$template = $parser->Parse('Build_Scheduler.xlsx'); is failing?
Currently I see no syntax or logic errors in the above program.
I am following the CPAN examples for the relevant modules exactly.
