         "162" : "0.000"
      }
   }

For above I wrote code:

print "content-type: text/html \n\n"; #HTTP HEADER
$dirname = "/ravikiran/html/JSONData.txt";
$dirpath = "$ENV{DOCUMENT_ROOT}$dirname";
sysopen(HANDLE, $dirpath , O_RDWR);
my %data;`enter code here`
while($line = <HANDLE>) {
chomp $line;
print $line;
}
close (HANDLE);

The input looks like JSON. Use the appropriate module:

use JSON;
my $s = from_json(join q(), <>);
