I'm not exactly familiar with what you're asking, but it sounds as if it would involve evaluating cell contents. That is outside of the scope of POI - it's a library for reading and writing various file formats, not a spreadsheet application that can evaluate the contents of those files.
(Also, please drop the habit of using multiple exclamation marks - one is enough to signal your meaning. Although at the end of a question you may want to use a question mark instead to make it look like a, well, question, instead of an order :-) )
