You could simplify your code a lot by working with hashes instead of arrays.
use List::Util 'sum'; while (<TABFILE>) { my @fields = split /\t/; my $identifier = shift @fields; my ($category, $group) = ($identifier =~ /^TS(\d+)(\w+)/); warn "Parse error", return unless $category && $group; # This may not be what you're doing, but change # this to do the calculations you need to do $sums{$group}->{$category} += sum(@fields); $totals{$group}->{$category} += @fields; } # Another way of cleaning up bad data foreach (keys %sums) { $sums{$_}->{CCFN30NT} += delete $sums{$_}->{CCCFN30NT}; $totals{$_}->{CCFN30NT} += delete $totals{$_}->{CCCFN30NT}; ... }
Also note that Excel can work with CSV or tab-delimited files natively, and more importantly, you can use formulas in Excel to calculate a lot of this. Your script need only output an Excel formula in a field (preceded with an equal sign) instead of calculating the value in advance.

Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":

  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or How to display code and escape characters are good places to start.
