Hello and welcome to The Board.
My personal view is that Guerilla Data Analysis (GDA) is still very much 'current' even though it was written during an earlier version of Excel. If I hadn't already bought it and saw it now, I would still buy it. It is also available as an eBook.
The only other book that I think comes close to GDA is Excel Gurus Gone Wild (also available as an eBook). However, this book is aimed at 'Reader Level' of Advanced and Ultra Advanced and does need careful study to understand the content.
