It is a simple tool to use, yet powerful.
The major features of a PivotTable are as follows −
Creating a PivotTable is extremely simple and fast
Enabling churning of data instantly by simple dragging of fields, sorting and filtering and different calculations on the data.
Arriving at the suitable representation for your data as you gain insights into it.
Ability to create reports on the fly.

Providing interactive reports to synchronize with the audience.
In this tutorial, you will understand these PivotTable features in detail along with examples. By the time you complete this tutorial, you will have sufficient knowledge on PivotTable features that can get you started with exploring, analyzing, and reporting data based on the requirements.
Creating a PivotTable
You can create a PivotTable from a range of data or an Excel table. You can start with an empty PivotTable to fill in the details, if you are aware of what you are looking for. You can also make use of Excel Recommended PivotTables that can give you heads up on the PivotTable layouts that are best suited for summarizing your data.
You will learn how to create a PivotTable from a data range or Excel table in the Chapter - Creating a PivotTable from a Table or Range.

You will learn how to apply the calculation types on a PivotTable in the Chapter - Summarizing Values by Different Calculation Types.
Updating a PivotTable
Once you have explored the data and summarized it, you need not repeat the exercise if and when the source data gets updated. You can refresh the PivotTable so that it reflects the changes in the source data.
You will learn the various ways of refreshing data in the Chapter – Updating a PivotTable.
PivotTable Reports
