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="$rep">
      <row>
        <cell text="Comp_Recid" />
        <cell text="ApplicationType" />
        <cell text="State" />
        <cell text="Count (*)" />
      </row>
      <loop name="inner">
        <row>
          <cell text="$companyid" />
          <cell text="$apptype" />
          <cell text="$state" />
          <cell text="$count" />
        </row>
      </loop>
    </worksheet>
  </loop>
</workbook>

It's all fine and dandy until someone has to look at the code.
