Contents of CSV sheet1, stored in hash table. 
$VAR1 = 'key_2';
$VAR2 = 'value_2';
$VAR3 = 'key_1';
$VAR4 = 'value_1';

This is not a hash table. This is a series of assignments of values to four independent variables. At most, this looks like an array broken up into pieces, which should be written as

@VAR = ('key_2', 'value_2', 'key_1', 'value_1');

In a perl hash table, values are associated to keys, and the values can be retrieved with the keys. 

%VAR = ( key_1 => 'value_1', key_2 => 'value_2');
print "value for key 2: '$VAR{key_2}'\n";
__END__
value for key 2: 'value_2'

Please read perldata. Done that (and trying what's stated there) you will be able to find out how to print values corresponding to keys.

perl -le'print map{pack c,($-++?1:13)+ord}split//,ESEL'
