Top Forums Shell Programming and Scripting Need to Preprocess a text file and convert into csv Post 302952700 by Don Cragun on Friday 21st of August 2015 03:46:24 AM

Yes, it is easy to do something like this with an awk script...

Normally, a CSV file would have the same number of fields in every output line. There doesn't seem to be anything in your input file that indicates how many fields are present in the data. (We know that it is at least 101 fields, but we have no idea how many zero fields should appear at the ends each output line.) How is your script supposed to determine the number of fields to include in the output?

A CSV file also usually uses a comma as the field separator, but you seem to want a space character as the field separator. Is that correct?

Will there ever be anything other than :1 at the ends of the input fields (other than the 1st field)? For example, if a line had a lot of ones and a few zeros, could the input use fields ending with :0 instead of :1 to produce a shorter input line? Is all of the data you want to process in this same format? For example, the "diabetes" files on the site you referenced are in a completely different format.

Will each input line have the same number of fields as in your sample input? Or, can the number of ones in input and output lines vary?

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
