The question does not have to be directly related to Linux and any language is fair game.

well I thought it would be cool if I echoed items and could place them columns and rows in excel. Not long ago I started learning how to use imagemagick and some its features. I started setting thing as variables and I thought it would be fun to learn how to set each variable in a column and start a new row. I dont really have anything just something I wanted to learn.
Well, I think independent from the language or command you use, the way to put data into a csv-file will always be, to split the line and putting the data into a list. As an example (Perl-code), when the delimiter in the lines is a ";"
my @data = split /;/, $line ;
afterwards @data (an Array) holds the data of the fields between the ";"
Now one could substitute (or set) the data
$data="my new data" ;
would put the text "my new data" into the fourth field of the array.
and join the array to a string
$newline = join /;/, @data ;
There are also solutions possible with sed or awk.
thats a good point... ascii (including .csv or .xml) is the most trans-portable format so dealing with .csv (which ms-excel can handle) is easier with trying to translate .xcl files into ascii without a gui.
i remember using a program that would transform open-office odf into ms-excel format (so you can do hundreds at a time) but i forget what it was called.
