## Excel

John Walkenbach is the author of several books on Excel. These are updated as new versions of Excel are released. I used his book Excel 2002 Power Programming With VBA as a primary reference for most of my work. I have ordered his most recent book Excel 2010 Power Programming With VBA. I expect to use it to bring my add-ins up to date. The site links to a blog page and some free stuff.
