How to Insert a Pivot Table The first step is to insert a pivot table into your workbook. Typically you will want to insert your pivot table on a new worksheet. After you create the pivot table you will see a list of fields in the task pane on the right side of the screen.
These fields are the columns in your data set. The Pivot Table Areas The pivot table contains four areas that you can drag the fields into to create a report. Filters area Rows area Values area The following diagram shows where each area of the pivot table is located on the report.

When you drag a field into the Rows area of the pivot table, all the unique values in that field will be displayed in the first column of the pivot. The pivot table removes all the duplicates in the field column of source data and only displays the unique values.
In my sample data set you can see the regions are listed more than once because we made sales in each region multiple times throughout the years. When I place the Region field in the rows area, each region is only listed one time in the first column of the pivot table.
Again, the pivot table automatically removes the duplicates and only displays the unique values. The layout of the source data is extremely important for this to work, and I will explain more about this below.
The Values Area The Values area displays the data values that we want to summarize in our pivot table report. When you drag a field into the Values area, the pivot table will automatically sum or count the data in that field. If the data in the field contains numbers, then the sum will be calculated.
If the data contains text or blanks, then the count will be calculated. The calculation type can be changed later to other functions like Average, Max, Min, etc. In this example I will place the Revenue field in the Values area.This book is part of Que’s exciting new Content Update Program, which provides automatic content updates for major technology improvements!
