<p>This release of HSSF does not yet support Formulas. I've been
focusing on the requests I've gotten in. That being said, if we get
more user feedback on what is most useful first we'll aim for that.
As a general principal, HSSF's goal is to support HSSF-Serializer
(meaning an emphasis on write). We would like to hear from you! How
are you using HSSF/POIFS? How would you like to use it? What features
are most important first?
