I have some interestingly formatted CSV I need to get into a Perl hash. One of the columns uses "s as the quote char, all other columns use 's. The " column has 's in it. See the "JOHNS FLYING DOG" row. The last time this data format was used, I wrote text editor regexes to turn the CSV data into a literal perl hash of array refs, then processes that data structure into a hash of hashes. I'd like a better solution than the previous one (I also lost the previous solution). How do I get this CSV into a Perl hash? I am not sure Text::CSV has the options to do it, and I couldn't easily find any other CSV parser engines on CPAN (everything seems to be wrappers around Text::CSV or CSV_XS). 
use Text::CSV::Hashify;
use Data::Dumper;

my $filename =  'bad.csv';
$obj = Text::CSV::Hashify->new( {
    file        => $filename,
    format      => 'hoh',
    key         => "PRODUCT CODE",
    quote_char          => "'",
    escape_char          => "|", #wont be found in the data, turn off 
+escaping
    auto_diag => 1,
} );
    
    
print Dumper($obj->all);
