I found the best way to learn Excel or any software program, for that matter, is to purchase a textbook. The best ones I have found for Excel are the Shelley Cashman series. They explain everything and they have a picture to show you what your page should look like. There are other book series such as "Simply Visual". These can be found in school bookstores, but a cheaper source might be Amazon.com (they will lead you to good second hand resources), Powells.com, to name two. If you spend more than $25, shipping is free and in Oregon there is no sales tax.
