A pivot table is a tool that you can use to summarize data when you have a lot of it in a worksheet. A pivot table can count totals, give an average of the data, or sort data â in addition to other things. In this article, we are going to go in-depth as we learn to create and work with pivot tables.

Danny Rocks, owner of the software training company The Company Rocks, explains that users can create a basic pivot table in as few as 10 mouse clicks.ivot tables work with the data available at the time of creation, though, and may not immediately update when the data changes or new data become available. Instead, you may need to refresh pivot tables or even completely recreate the tables after data changes in order to reflect the most current information.
