Perl将数据从哈希转储到电子表格

Question

我有一个带键和值（数组）的哈希。我想将它们转储到电子表格

%hash
   key1 -> foo bar 
   key2-> john adam gill
   key3-> apple banana mango orange

代码：

use strict;
use warnings;
use Excel::Writer::XLSX;

my $workbook = Excel::Writer::XLSX->new( 'c:\TEMP\filename.xlsx' ); 
my $worksheet = $workbook->add_worksheet();

my $row = 1;
my $col = 1;

foreach my $k (keys %hash)
{
    $worksheet->write($row, $col)->{Value} =  $k;                # title
    $worksheet->write($row, $col++,)->{Value} =  $hash{$k};     # value
    $row++;
}

当前输出
无法调用方法＆＃34; add_worksheet＆＃34;在未定义的值上

期望输出

Answer 1

似乎Excel::Writer::XLSX->new失败了。在致电new后添加此代码，看看出了什么问题：

if (not defined $workbook)
{
    die "Failed to create spreadsheet: $!";
}
