It provides a easy to use yet powerfull and flexible way to get +data from Spreadsheets into LaTeX. + +In difference to other existing solutions, exceltex does not seek for +making the creation of tables in LaTeX easier, but to get data from +Spreadsheets in into LaTeX as easy as possible. + +The excel fileformat acts as an interface between the spreadsheet +application and exceltex beacause it is easily accessible via the +Spreadsheet::ParseExcel Perl module and because most spreadsheet +applications are able to read and write excel files. + + + + + REQIREMENTS + +Exceltex depends on the perl module Spreadsheet::ParseExcel and the +LaTeX Packages ulem and color. + +Currently a Unix like operating system is required, cygwin on windows +should work also. + + + + + + LATEX COMMANDS + +Exceltex provides two commands to include single cells and cell-ranges +for tabulars. Load the exceltex LaTeX package via +\usepackage{exceltex}. + + \inccell{foo.xls!results!B9} + includes cell B9 from sheet results in file foo.xls + + \inctab{foo.xls!results!B2!C15} + includes the 14 rows between B2 and F15 from sheet results + in file foo.xls in LaTeX' tabular format ('&' separated rows + ended by \\) + +For both commands you may omit specifying the file (foo.xls) if it has +the same basename (foo) as the LaTeX file (foo.tex). + + + + + USAGE + +Mark cells and tabulars for inclusion with the \incell and \inctab +commands. Then run latex, exceltex and latex again. + +The following Example demonstrates the usage of exceltex: + +--- snip --- +\documentclass{article} +\usepackage[options]{exceltex} + +\begin{document} + +\title{a brief introduction to exceltex} +\maketitle + +\section{including single cells} + +You can include contents of cells with the \\inccell command. Example: +Cell A1 on sheet 'Sheet1' of file foo.xls is: +\inccell{foo.xls!Sheet1!A1} + + +\section{including tabulars} + +this is as easy as including single cells. + +\begin{tabular}{lll} + \hline + column 1 & colum 2 & colum 3 \\ + \hline + \inctab{foo.xls!Sheet1!A1!C5} + \hline +\end{tabular} + +\end{document} +--- snap --- + +now, run latex, then exceltex and latex again. + +The \inctab command does nothing else than provide the requested cells +in LaTeX' tabular format - colums are separated with a '&', each line +is endet with a line break (\\). This gives you a maximum of +flexibility and the freedom to use whatever tabular package you want. + + +Currently one package option is supported. +\usepackage[cellrefs]{exceltex} will write cell data to files named by +filename, workbook and cell instead of sequentially numbered files. + + + + + PROBLEMS + +* Exceltex cannot read Excel files created by Spreadsheet::WriteExcel + (see Spreadsheet::ParseExcel documentatin for details). + +* Workbook names must not include problematic characters (LaTeX + control Characters) (^,_,$,%,&,!). Just use Letters, Numbers and a + Minus as spearator. + +* when using the cellrefs package option, whitespaces are also + forbidden in workbook names and filenames. These are LaTeX + limitations, i think. + + + + + + HOW IT WORKS + +The first LaTeX run writes an entry for each \inctab, \inccell command +to a spearate index file (\jobname.exltx). This index is then read by +the exceltex helper script, which actually extracts the ordered data +and writes it to sequentially numbered files in the directory +\jobname-exltx. The \inctab and \inccell are then simply including +these files via a \InputIfExists{} command on the following latex runs. + + + + + TODO + +Support for other formats than excels would be appreciating. There is +maybe a chance to get OpenOffice Calc working. There is now a module +OpenOffice::Parse::SXC on cpan which could to the job for Openoffice, +but it seems quite new and is not includeded in Ubuntu yet. On the +other hand, support for different fileformats would yield a naming +problem, at the time i started with exceltex (in 2004) there was only +Spreadsheet::ParseExcel, so the name exceltex .... + + +The newest version of Exceltex is available at the following url: +http://www.physik.uni-freiburg.de/~doerr/exceltex + + + + + COPYING + +exceltex is Copyright 2004-2006 by Hans-Peter Doerr +<doerr@cip.physik.uni-freiburg.de> + +This is free software; see the source for copying conditions.
