Coverting csv file to binary

Henry Chua — Tue, 05 Apr 2005 03:48:06 GMT

Hi guys,

Is there a way to covert csv file to its binary equivalent. I have attached the sample files.

Hope u guys can help me out..
thanks!!

Henry

attached is its binary file equivalent..

can you tell us what the "binary" format is?

I've looked at the binary file but it has things missing from the original file.

I even saw a backspace character in it (which is weird for a file format).

How did you get the cvs file into that binary format?

H.Merijn Brand (procura — Tue, 05 Apr 2005 07:36:56 GMT

# perl -MText::CSV_XS -le'$c=Text::CSV_XS->new({binary=>1});while(<>){$c->parse($_);print$c->fields}' file.csv > file.dta

BUT!

M$ has never been able to read the specs. CSV is shorthand for COMMA Separated Values, and guess what M$ uses? Right, a semicolon. So in order to convert microshit generated csv files, you need

# perl -MText::CSV_XS -le'$c=Text::CSV_XS->new({binary=>1,sep_char=>";"});while(<>){$c->parse($_);print$c->fields}' file.csv > file.dta

If you are trying to import the cvs file into M$ decel (I mean excel) then just use the wizard and change the default from a ; to a ,

Hi MeiJin,

Sorry I am new to Perl, can u explain how your script actually works.. I tried running it on my system. doesnt seem to work

Hi Harry,

What I really want to do is to convert csv file to its binary equivalent. This binary file is generated by a customise program, in actual I am not even sure if the conversion is possible.. just trying my luck..

Thanks!! =)

I've never before seen my name spelt like that :)

perl -MText::CSV_XS -le'$c=Text::CSV_XS->new({binary=>1,sep_char=>";"});while(<>){$c->parse($_);print$c->fields}' file.csv > file.dta

is more verbose,as a script, more or less the same as (with comments):

--8<--- csv2bin.pl
#!/opt/perl/bin/perl
# this line tell where your perl resides

use strict; # Don't allow ambiguous code
use warnings; # Warn me wherever appropriate

use Text::CSV_XS; # use the Text::CSV_XS module.
# Should be installed from CPAN or bundled in the port you got

my $csv = Text::CSV_XS->new ({ # create a new csv handle
binary => 1, # that uses binary data
sep_char => ";", # and a semicolon as separator
});

# Now parse the input lines
while (<>) {
$csv->parse ($_); # break down as valid csv
print $csv->fields; # and print the fields as binary
}
-->8---

First check if you have perl, and what version:

# perl -v

If you don't have it (yet), you can get it from my site, and my builds include CSV_XS

My HP ITRC site pages can be found at (please use LA as primary choice):

Hi Merijn,

Sorry for getting your name wrong. =p

I have gotten this when i probed the machine.

This is perl, version 4.0

$RCSfile: perl.c,v $$Revision: 4.0.1.8 $$Date: 1993/02/05 19:39:30 $
Patch level: 36

Copyright (c) 1989, 1990, 1991, Larry Wall

Perl may be copied only under the terms of either the Artistic License or the

Will this version work? Where can I grt the "CSV_XS" for this version?

Thank u for your help..

=)

Henry

Perl 4 is basically useless except to run the q4 dump analyzer. Perl 5 should be downloaded from software.hp.com and installed on your machine.

Henry Chua — Wed, 06 Apr 2005 11:15:00 GMT

Hi Merijn,

I gotten this when I try to run the script..
"Can't locate Text/CSV_XS.pm in @INC (@INC contains: /usr/lib/perl5/5.8.0/i386-l.
BEGIN failed--compilation aborted at ./test line 7."

do you know what i did wrong? how can i get the csv_xs.pm package?

Hi guys,

Manage to fix the problem and make the module work. However, I was wondering whether i could modify the script to convert binary to csv as well..

can be done?

Best regards
Henry

If you pass out some points to reflect the appreciation of the answers, I could give you the hint to use unpack or split and Text::CSV_XS to do the reverse. I could even bshow you some code.

No problem... ^_^

Re: Coverting csv file to binary

H.Merijn Brand (procura — Sat, 09 Apr 2005 14:15:42 GMT

OK, here's a real-life script that would convert almost anything text-like to csv or M$-Excel. You don't have (nor can get) PROCURA::Diac, so you need to find other methods to deal with Unicode conversions (Encode is a good start)

Spreadsheet::WriteExcel and Date::Calc are both included in my perl builds and are available on CPAN. The advantage of writing xls yourself, instead of having M$-Excel do it on import or open is that you have control over the dates, instead of having M$ fuck-up all valid dates to be forced to braindead US format

Also attached to have your script retain format. Hey, I even have a usage sub :)

Hi Merijn,

Many thanks for the script. I am in the midst of digesting - quite a big for my level.

One last thing I would like to know is whether converting binary to text is possible? if so can I used CSV_XS to achieve this?

I am terribly sorry for constant queries. Thanks for your invaluable assistance.

Best regards
Henry

H.Merijn Brand (procura — Mon, 11 Apr 2005 03:55:16 GMT

Binary to text is to vague a goal to solve.

Do you consider UTF8 binary? Or Unicode? Or even iso-8859-1?

If your defenition of "Text" is plain US-ASCII 7 bit, yes, it's probably possible, most likely possible even. But your conversion will not be lossless

What is "Binary" and what is "Text". That is the crucial question in your quest. Once you can answer that unambigouously, my answer would probably be "yes"

If your def of Binary is "fixed width records" that should be converted to html or other text based data files, do

# man perlpacktut

and teach yourself unpack

Enjoy, Have FUN! H.Merijn

Re: Coverting csv file to binary

Henry Chua — Tue, 12 Apr 2005 08:55:14 GMT

Hi Merijn,

From a look at a binary file is it possible to tell which coding it is using? For example the binary file I provided in the begining of the query, can you tell which format is it using?

And many thanks, You have been really been a great help, sorry if my question look weird to u..

Regards
Henry

Re: Coverting csv file to binary

H.Merijn Brand (procura — Tue, 12 Apr 2005 09:31:14 GMT

Your .null file is a LIF file, which is pretty much a binary format :)

a5:/tmp 102 > file *.null
226232.null: lif file
a5:/tmp 103 > lifls *.null | head
WS_FILE

a5:/tmp 104 >

There are several LIF commands:

lifcp, lifinit, lifls, lifrename, and lifrm

a5:/tmp 108 > lifls -l *null
volume HFSLIF data size 1052 directory size 1
filename type start size implement created
===============================================================
WS_FILE -5791 2 121 20200080 00/00/00 00:00:00
a5:/tmp 109 >

Now, maybe, you might mean that you want to know the format of WS_FILE

a5:/tmp 110 > lifcp 226232.null:WS_FILE .
a5:/tmp 111 > file WS_FILE
WS_FILE: data
a5:/tmp 112 >

Looking at the hex-dump of WS_FILE, it looks very parsable and very binary (about Volt, Ampere, and Ohm). Since I have no idea what it is, I cannot give you any guidelines here
