I'm tyring to create the following format of hash:
    {                                      
        "test": [          
            {                              
                "group": "ABC1",            
                "values": [
                    "abc",                
                    "xyz"
                ]                          
            },                             
            {                              
                "group": "ABC2",            
                "values": [
                    "abc2",                
                ]                            
            },                             
            {                              
                "group": "ABC3",            
                "values": [            
                    "xyz3"
                ]                             
            }                              
        ]                                  
    }

I iterate over my data the perform the following code on each line:
    open(my $fh, '<', "$file_path") or return 0;
    while (my $line = <$fh>) {
    
        # ...........
        # ...........
        # Additional operations of the lines of the file
        # ...........
        # ...........
        
        
        my %a; # temp hash
        $a{"group"} = $group;
        if (defined($href->{"values"})) {
            $a{"values"} = [sort(uniq($value,@{$href->{"values"}}))];
        } else {
            push(@{$a{"values"}},$value);
        }
        push(@{$href->{"test"}},\%a);
    }

I don't like how it looks, it is not clear and a bit mess.
Is there a way to make the code shorter and maybe without using the temp hash and if-else block?
EDIT: I found out that it actually won't do what I need - it will not push the value in the same array of the group. Not sure how to fix it yet.
EDIT-2: I'm sorry if my question was not understandable. I though about it and from the comments I leraned that I need to clerify my question (sorry again). I have talked about the inner structure but actually the final structure which I need is: 
{

    "root": [

            "test": [          
                {

I want to iterate though a file of data, parse it and extract group and values. The currect way I use: 
sub parse_file {
    my ($file_path,$href) = @_;

    open(my $fh, '<', "$file_path") or return 0;
    while (my $line = <$fh>) {
        chomp($line);
        unless ($line =~ /\A[^,]+(?:,[^,]+){5}\z/) {
            next;
        }

        my ($key,$group,$value,$version,$file,$count) = split(/,/,$lin
+e);

        push @{ $href->{test} }, {
            group  => $group,
            values => [ sort uniq $value, @{ $href->{values} // [] } ]
        };
    }
    close ($fh);

    return 1;
}

foreach my $dir (sort(@list_of_dirs)) {
    my ($all,%data);
    $all = $dir."/"."galish";
    prase_results_raw($all,\%data);
    push(@all_data,\%data);
}

It does what I need when there are no multiple values for the same group.
For multiple values for the same group I'll get: 
{

If you take a look closely, you'll see duplicates of the same group name in the same test.
