Perl script to merge cells

---------- Post updated at 12:59 AM ---------- Previous update was at 12:54 AM ----------

I am using below code to read files from a dir and print to excel.

Code:
open(my $in, '<', $file) or die "Could not open file: $!";
        my $rowCount = 0;
		my $colCount = 0;
        while(<$in>)
        {
			my @elements = split(',',$_);
			foreach my $el(@elements)
            {
				$wrksheet->write($rowCount,$colCount,$el);
				$colCount++;
            }
            $colCount = 0;
            $rowCount++;
        }

Show the input you have and the output you want.

We also would need to see the use statements as well as what you used to create the $wrksheet object.

Below is the complete code which works great converting all csv files(sorted based on column1) in dest directory to a single xls with multiple tabs.

Code:
use warnings;
use Spreadsheet::WriteExcel;
my $dest = '/home/dest';
my $workbook = Spreadsheet::WriteExcel->new("test.csv");
chdir $dest or die "no such directory: $!";
if ( -d $dest ) {
    opendir my $dh, $dest or die "can't open directory: $!";
	my @files = sort { $a cmp $b } readdir($dh);
	while ( my $file = shift @files ) {
        chomp $file;
        next if $file eq '.' or $file eq '..';
        my $sheetname = `basename $file | cut -d. -f1`;
        my $wrksheet = $workbook->add_worksheet($sheetname);
        open(my $in, '<', $file) or die "Could not open file: $!";
        my $rowCount = 0;
		my $colCount = 0;
		$colCount = 0;
        while(<$in>)
        {
			my @elements = split(',',$_);
			foreach my $el(@elements)
            {
				$wrksheet->write($rowCount,$colCount,$el);
				$colCount++;
            }
            $colCount = 0;
            $rowCount++;
        }
    }
}

The xls file(with multiple rows on each sheet) which i am generating with above code will look like below:

Code:
abs-pq        tfr23 	 12345
abs-pq	tfr24	         12843
abs-pq       tfr24           12435
abs-pqrst	rts09           19923|23141
abs-pqrst	rts10	         23456
tbs-pqrst	tfr25	          21938|22143
tbs-pqrst	zzz0z	          2414|5213|4306

column1 duplicates needs to be removed and merged as one cell.
column2 duplicates needs to be removed based on merged column1 only.( first three lines of below )
column3 should be unchanged.

need output like below(ignore ___ just filled gaps to show difference) :
Code:
abs-pq  tfr23 12345
______tfr24 12843
___________12435
abs-pqrst  rts09 19923|23141
_________rts10	23456
tbs-pqrst	tfr25	21938|22143
_________zzz0z	2414|5213|4306

any help in extending my original code to meet the requirement is greatly appreciated.

I cannot tell what the output you want is supposed to look like. Try posting your output again, this time with code tags, [code] stuff [/code]

Code:
INPUT:
abs-pq	        tfr23	12345
abs-pq	        tfr24	12843
abs-pq	        tfr24   12435
abs-pqrst	tfr24   19923|23141
abs-pqrst	rts10	23456
tbs-pqrst	tfr25	21938|22143
tbs-pqrst	zzz0z	2414|5213|4306

OUTPUT REQUIRED:
abs-pq	        tfr23	  12345
	        tfr24     12843
			  12435
abs-pqrst	tfr24     19923|23141
        	rts10	  23456
tbs-pqrst	tfr25	  21938|22143
	        zzz0z	  2414|5213|4306

NOTE: cell B4 also have tfr24 but it should not be merged since column1 value is different.

Something like:
Code:
#! /usr/bin/perl

use strict;
use warnings;
use Spreadsheet::WriteExcel;

my $file = shift @ARGV;
my $workbook = Spreadsheet::WriteExcel->new($file) or die "can't create worksheet: $!";

my $dest = shift @ARGV;
chdir $dest or die "no such directory: $!";
opendir my $dh, '.' or die "can't open directory: $!";
my @files = sort grep { m{^[^.]} } readdir($dh);
close $dh; 

foreach my $file (@files) {
    open my $in, '<', $file or die "Could not open file: $!";

    $file =~ s{\..*$}{};
    my $worksheet   = $workbook->add_worksheet($file);

    my @prevRow = ();
    my $row = 0;

    while(<$in>) {
        my @currRow  = split(',', $_);
        my $col = 0;

        while ($col < @currRow) {
            last if @prevRow < $col || $currRow[$col] ne $prevRow[$col];
            $worksheet->write($row, $col, '');
            $col++;
        }

        while ($col < @currRow) {
            $worksheet->write($row, $col, $currRow[$col]);
            $col++;
        }

        @prevRow = @currRow;
        $row++;
    }
}

Invoked with:
Code:
scriptname workbookfile sourcedir...

Some notes:
  • if ( -d $dest ) { was not needed, the previous chdir would have failed if $dest was not a directory.
  • chomp $file is not needed, a trailing newline is an acceptable (if not appreciated) character in a directory entry
  • Be reluctant to use system calls in a perlscript. In this case, my $sheetname = `basename $file | cut -d. -f1`; was replaced by $file =~ s{\..*$}{}; as $file is already a "basename" and you were just trimming off everything after the first ".".
