The output file required is in .csv format. How can I attach it here?
Rather than uploading well over a hundred kilobytes of data, it would be much better to:
  1. describe the number of fields, number of bytes / line, and total sizes of your real input and expected output files,
  2. provide abbreviated (fewer fields and fewer lines, but enough to show the structure of your data) sample input (in CODE tags) in your post instead of hoping that some of the volunteers here have space to burn on the systems they use to try to help you,
  3. provide sample output corresponding to your sample input (also in CODE tags), and
  4. describe in English what processing needs to be done to produce the output you want from the input files you have supplied (including case translations, input and output field separators [and when an input file uses space as a field separator and as data in a field, explain how you know which spaces are data and which spaces are separators]).

Don't just show us the code you have written. Explain what it is trying to do and how that relates to producing the output you want. We can help you fill in missing pieces of code once we understand what you're trying to do.

If you absolutely must upload a .csv file; assuming you have the desired output in a file named output.csv, move or link it to output.txt and upload output.txt.

Text::CSV::Encoded::Coder::EncodeGuess(3pm)		User Contributed Perl Documentation	       Text::CSV::Encoded::Coder::EncodeGuess(3pm)

NAME
Text::CSV::Encoded::Coder::EncodeGuess - Text::CSV::Encoded coder class using Encode::Guess SYNOPSIS
use Text::CSV::Encoded coder_class => 'Text::CSV::Encoded::Coder::EncodeGuess'; use Spreadsheet::ParseExcel; my $csv = Text::CSV::Encoded->new(); $csv->encoding( ['ucs2', 'ascii'] ); # guessing ucs2 or ascii? $csv->encoding_to_combine('shiftjis'); my $excel = Spreadsheet::ParseExcel::Workbook->Parse( $file ); my $sheet = $excel->{Worksheet}->[0]; for my $row ( $sheet->{MinRow} .. $sheet->{MaxRow} ) { my @fields; for my $col ( $sheet->{MinCol} .. $sheet->{MaxCol} ) { my $cell = $sheet->{Cells}[$row][$col]; push @fields, $cell->{Val}; } $csv->combine( @fields ) or die; print $csv->string, " "; } DESCRIPTION
This module is inherited from Text::CSV::Encoded::Coder::Encode. USE
Except for 2 attributes, same as Text::CSV::Encoded::Coder::Encode. encoding_in $csv = $csv->encoding_in( $encoding_list_ref ); The accessor to an encoding for pre-parsing CSV strings. If no encoding is given, returns current $encoding, otherwise the object itself. $encoding_list_ref = $csv->encoding_in() When you pass a list reference, it might guess the encoding from the given list. $csv->encoding_in( ['shiftjis', 'euc-jp', 'iso-20022-jp'] ); If it cannot guess the encoding, the first encoding of the list is used. encoding $csv = $csv->encoding( $encoding_list_ref ); $encoding_list_ref = $csv->encoding(); You can pass a list reference to this attribute only: * For list data consumed by combine(). * For list reference returned by getline(). In other word, in "combine" and "print", it might guess an encoding for the passing list data. If it cannot guess the encoding, the first encoding of the list is used. SEE ALSO
