Here were some things that I through together really quick over a couple of days.
A simple stream editor, can be used when you don't know SED that well or you need more than just regex and such. This Excel JDom code doesnt really work, but if you transform an Excel 2003 document, ideally you want XSLT but if you want a java way to parse that document, simple code mind you, here you go. The last one is a JSP page for processing SQL sending out SQL statements. It is ugly, but I always hate having to rewrite a web page when I dont have a template around.
