for my $row(1 .. $eSheet->{MaxRow})
{
 next unless (defined $eSheet->{Cells}[$row][$col]);
my $master_key=$eSheet->{Cells}[$row][0]->Value;

for my $col(1 .. $eSheet->{MaxCol})
{
next unless (defined $eSheet->{Cells}[$row][$col]);
my $key= $eSheet->{Cells}[0][$col]->Value;
my $value = $eSheet->{Cells}[$row][$col]->Value;
$data{$master_key}->{($key)}=$value;
}

    What does your code output?

    What output do you expect instead?

      Expected Output

        { 
'1'=> {
      'clz=>'nit'
      'degree'=>'ph.d',
      'name'=>'teja'
      },
'1'=> {
      'clz=>'iit'
      'degree'=>'M.tech',
      'name'=>'teja'
      },####This block not coming in output

'2'=>{
       'clz=>'mit'
      'degree'=>'ravi',
      'name'=>'B.Tech'
}
};

        A hash cannot have multiple values for the same key. You will need to rethink your data structure.

        Consider storing array references as values instead of hash references as values:

         { 
'1'=> [{
      'clz=>'nit'
      'degree'=>'ph.d',
      'name'=>'teja'
      },
      {
      'clz=>'iit'
      'degree'=>'M.tech',
      'name'=>'teja'
      }],####This block not coming in output
'2'=>[{
       'clz=>'mit'
      'degree'=>'ravi',
      'name'=>'B.Tech'
}]
};

        This change will also need changes in your code on how you fill the data structure and how you output your data structure.
