veeru612 has asked for the wisdom of the Perl Monks concerning the following question:

Hello oh great monks of perl, I am very very new to perl - started today. I have multiple files in a folder and these files have the same format and the data is arranged in exact same way in all of them. I need to extract 2 columns of each file and put them all in one spreadsheet preceeded by the file name. this is what I have written (copied from one of the threads on this site) to extract data and put in an excel,, then grab first two columns from all the files in the folder and put them in one giant spreadsheet. thank you so much for the help,,
#!/usr/bin/perl -w use strict; use Spreadsheet::WriteExcel; my $workbook = Spreadsheet::WriteExcel->new('test.xls'); my $worksheet = $workbook->add_worksheet(); open INPUT, 'data.SSM' or die "Couldn't open file: $!"; $worksheet->write($.-1, 0, [split]) while <INPUT>;
I wrote another but its not working, am pretty sure it's not the right code/is full of errors.
#!/usr/bin/perl -w use strict; use Spreadsheet::ParseExcel; use Spreadsheet::WriteExcel; my %count; my $directory = "c:\\perl test scripts"; my $workbook = Spreadsheet::WriteExcel->new('test.xls'); my $worksheet = $workbook->add_worksheet(); opendir(DIR, $directory ) || die "Unable to open directory - $!\n"; my @files = grep /\.txt/, readdir( DIR ); closedir( DIR ); foreach my $file (@files) { open( FH, "$directory\\$file" ) || die "Unable to open $file - $!\n"; while( <FH> ) { $worksheet->write($.-1, 0, [split]) while <FH>; } close( FH ); }

    Please edit your question to use the <code> tags to format the code better.

    What is the error you are getting? The second code is working for me. Except that you don't need Spreadsheet::ParseExcel. Because, you are not Parsing any excel files.
    Also change this : <#!/usr/bin/perl -w> to this: #!/usr/bin/perl -w. In your first code.

      Hello Sir, Please forget the first code, but in the 2nd code it says it cannot parse the formula and nothing gets written in the excel file, :(

        Which Formula? I can't see any in your second code. Except, there is a part of the code you are not showing.

    It looks like you are using the default var $_ to hold the data to be written to the excel file. Try storing the data to be written to the excel file in its own variable. You are relying on the excel module to read the default var and it may not be correctly.
