Hi All, Thanks for all your comments. I think I have more questions than I initially had. Which is good ! Now I understand the XY problem. I have a database which has 12 tables. The keys are column names from the excel sheet. This is my primary table and the rest in one to many relationship with this table. I have one value for the primary column in my LI table(COLUMN NAME LI) and can have multiple values for different columns in the same or different table. my $li_insert = "insert into LI values(LI_SEQ.nextval,?,?,?,?,?,?,?,?,?,sysdate,?,?,?,?)"; my $mechanism_insert = "insert into mechanism (TAGET,ACTIONTYPE,ID,LI_ID) values(?,?,MECH_SEQ.nextval,LI_SEQ.currval)"; Here one LI_ID can have multiple action_type or TAGET. So I want my script to be able to insert 5,2,1,12 6,1,2,12. The data would be like this: { 'taget '=> 5,6, 'Action_type' =>2,1 } in the excel sheet it actually comes as joined with a pipe operator I split them to have an array in a subroutine. How could I achieve this type of insertion if I keep them joined? Hope this is clear now!Let me know if you need any more details. 
# to get each hash from an array of hash 
foreach my $results(@$hash_of_excel){
 
 my $specificresults = GroupResults($results); 
 
}

sub GroupResults{
#to getonly the relevant columns(excel) for each table in the database
+.
#%details is a global hash tha holds different tables and their corres
+ponding column 
 my( $AllRecords )= @_;
 my %specificResults;
 
  for my $info (keys %details){
    $specificResults{$info}{$_} = $AllRecords->{$_} for @{$details{$in
+fo};

   }  
  }

 
  return \%specificResults;
 
}

sub SomethingUnPipeModifyRecord {
#convert the joined values to array of values 
    my( $rec ) = @_;
    for my $val( values %$rec ){
        my $newval = [ split /\|/, $val ];
        $val = $newval;
        
    }
    return $rec;
}

sub insertLI{
my ($li_results )= @_; 
 my $li_array_values = SomethingUnPipeModifyRecord($li_results); 
}


sub insertMech{
my ($mech_results ) = @_; 
my $mech_array_values = SomethingUnPipeModifyRecord($mech_results);
