Sane

You shouldn't need any software. It's a fairly simple task to do in any server-side scripting language. You can probably find snippets for it all around the Internet.

For example, in PHP... open the file with $my_string = file_get_contents("my_file.txt"), read it in line by line, then split each line into an array of fields with $fields = explode(",", $line), then display it however you feel.
