kwaping has asked for the wisdom of the Perl Monks concerning the following question:

I am trying to use Excel::Template (hi dragonchild!) to create an Excel workbook. Each worksheet should be titled with the name of a sales rep, and on that page should be four columns of data. Here's the relevant code.
Building the hash: 
foreach my $row (@data) {
  push @{$hash{$row->[0]}}, {
                  companyid =>  $row->[1],
                  apptype   =>  $row->[2],
                  state   =>  $row->[3],
                  count   =>  $row->[4],
                };
}

Sample data: 
%hash = (
          'One' => [
                          {
                            'apptype' => 'xxx',
                            'count' => '123',
                            'companyid' => 'xxx',
                            'state' => 'xx'
                          },
                          {
                            'apptype' => 'xxx',
                            'count' => '123',
                            'companyid' => 'xxx',
                            'state' => 'xx'
                          },
                          {
                            'apptype' => 'xxx',
                            'count' => '123',
                            'companyid' => 'xxx',
                            'state' => 'xx'
                          }
                        ],
          'Two' => [
                      {
                        'apptype' => 'xxx',
                        'count' => '123',
                        'companyid' => 'xxx',
                        'state' => 'xx'
                      },
                    ]
        );

My first stab at building the params, not even close to working: 
foreach my $rep (sort keys %hash) {
  $template->param(
            REP =>  {
                  rep   => $rep,
                  DATA  => $hash{$rep}
                },
          );
}

[download]
And the XML to build the worksheet: 
<workbook>
  <loop name="REP">
    <worksheet name="$rep">
      <row>
        <cell text="QM Distribution" />
      </row>
      <row>
      </row>
      <row>
        <cell text="Comp_Recid" />
        <cell text="ApplicationType" />
        <cell text="State" />
        <cell text="Count (*)" />
      </row>
      <loop name="DATA">
        <row>
          <cell text="$companyid" />
          <cell text="$apptype" />
          <cell text="$state" />
          <cell text="$count" />
        </row>
      </loop>
    </worksheet>
  </loop>
</workbook>

Any suggestions to help me get this working are appreciated!

Update: fixed some obviously bad syntax in the param code.

Re: Excel::Template and a hash of arrays of hashes

    I can't help directly but if, as the docs say, you're looking for a data structure similar to that used by HTML::Template this may help get you started.

    #!/usr/bin/perl 

use strict;
use warnings;
use HTML::Template;
use Data::Dumper;
$Data::Dumper::Indent = 1; 

my %h = get_hash();

my @outer;
for my $rep (keys %h){
  my @inner;
  for my $detail (@{$h{$rep}}){
    push @inner, $detail;
  }
  push @outer, {
    rep => $rep,
    inner => [@inner],
  }
}

my $param = {outer => [@outer]};

print Dumper $param;

exit;

# the following not directly relevant

my $t = HTML::Template->new(filename => 'kwaping.html')
  or die "can't parse template: $!";

$t->param($param);
print $t->output;


sub get_hash{
  
  return (
    'One' => [
      {
        'apptype' => 'xxx',
        'count' => '123',
        'companyid' => 'xxx',
        'state' => 'xx'
      },
      {
        'apptype' => 'xxx',
        'count' => '123',
        'companyid' => 'xxx',
        'state' => 'xx'
      },
      {
        'apptype' => 'xxx',
        'count' => '123',
        'companyid' => 'xxx',
        'state' => 'xx'
      }
    ],
    'Two' => [
      {
        'apptype' => 'xxx',
        'count' => '123',
        'companyid' => 'xxx',
        'state' => 'xx'
      },
    ]
  );

}

      Thank you wfsp, that did the job perfectly! I owe you a beverage of your choice sometime.

      The code: 
      my @outer;
foreach my $rep (sort keys %hash) {

  my @inner;

  foreach my $detail (@{ $hash{$rep} }) {
    push @inner, $detail;
  }

  push @outer,  {
                  rep => $rep,
                  inner => \@inner,
                }
}

$template->param( { outer => \@outer } );

      The XML: 
      <workbook>
  <loop name="outer">
    <worksheet name="$rep">
      <row>
        <cell text="Comp_Recid" />
        <cell text="ApplicationType" />
        <cell text="State" />
        <cell text="Count (*)" />
      </row>
      <loop name="inner">

          <cell text="$companyid" />
          <cell text="$apptype" />
          <cell text="$state" />
          <cell text="$count" />
        </row>
      </loop>
    </worksheet>
  </loop>
</workbook>
