Here is my code : 
#!/usr/bin/perl

@FILES = glob("*.txt");
foreach my $file (@FILES) {
    open my $fh, '<', $file;
    (my $fileName = $file) =~ s/\.[^.]+$//;
    open(my $output, '>', $fileName.".csv") or die "Could not open fil
+e '$fileName' $!";
    my @category;
    my @Detail;
    
    
    print $output "";    
    while (my $line = <$fh>) {
        
        chomp $line;
        @tokens = split /\|/,  $line;
        
        chomp(@tokens);
        
        $objectName=$tokens[0];
        
        if($objectName ne ""){
            my @objectFields;
            $size = scalar(@tokens);
            @tokens = @tokens[1..$size];
            foreach my $token (@tokens){
                $token =~ s/\r|\n//g;
                push @objectFields,$token;
            }    
            if($objectName eq "IFB Northpole"){
                @Detail=@objectFields;    
            }elsif($objectName eq "Walmart"){
                @category=@objectFields;
            }elsif($objectName eq "Chicken"){
                @category=@objectFields;
            }elsif($objectName eq "Beef"){
                my @item = (@Detail,@category,@objectFields);
                print $output join("|", @item,@removeemptylines)."\n";
                
            }
            
            
        }
