Top Forums UNIX for Dummies Questions & Answers Multiple excel files processing on unix Post 302291903 by ShawnMilo on Thursday 26th of February 2009 02:24:47 PM

If the tool you have is the only way you can process Excel files from your working environment, then it seems like it's not possible to concat them, since they're in binary format, and concatenating them will make the file either unusable to the ETL tool, or it will only read the first file and stop at the first end-of-file indicator.

However, is there any chance that you can get at the output of your ETL app, and concatenate the output of the three files before they're moved on to the next step?

If you can somehow get the XLS files converted to CSV and combine them before processing then you might be able to pull it off -- I'm sure your ETL tool can process a CSV file as an Excel spreadsheet if it can read the XLS format. There are Unix tools that can read XLS and export them as comma-delimited or tab-delimited files, such as the abtab (abstract table) utilities. I used them for two years at my old job.

abtab - Google Code (I don't know how up-to-date the Google Code files are compared to the in-house version I was using, but it should work.)

NAME
Test::Excel::Template::Plus - Testing module for use with Excel::Template::Plus SYNOPSIS
use Test::More tests => 1; use Test::Excel::Template::Plus; my $template = Excel::Template::Plus->new( engine => 'TT', template => 'test.tmpl', config => { INCLUDE => [ '/templates' ] }, params => { ... } ); $template->write_file('test.xls'); # compare the file we just made with # an existing example file ... cmp_excel_files("test.xls", "t/xls/test.xls", '... the excel files matched'); DISCLAIMER
This module is woefully incomplete. It works for my very basic purposes right now, but it is surely going to need lots or work in the future to make it really usable. DESCRIPTION
This module attempts to provide a means of testing and comparing dynamically generated excel files. Currently it only supports comparing two excel files for some approximation of strutural (values within cells) and visual (formatting of said cells) equivalence. As a by product of the implementation, elements may get compared which don't really need comparing, and things which do need comparing may be skipped. This will get refined as time goes by and the module is used in more heavyweight situations. FUNCTIONS
cmp_excel_files($file1, $file2, $msg) BUGS
All complex software has bugs lurking in it, and this module is no exception. If you find a bug please either email me, or add the bug to cpan-RT. AUTHOR
