A PivotTable is an interactive way to quickly summarize large amounts of data. You can use a PivotTable to analyze numerical data in detail, and answer unanticipated questions about your data. A PivotTable is especially designed for:

Querying large amounts of data in many user$-$friendly ways.

Subtotaling and aggregating numeric data, summarizing data by categories and subcategories, and creating custom calculations and formulas.

Expanding and collapsing levels of data to focus your results, and drilling down to details from the summary data for areas of interest to you.

Moving rows to columns or columns to rows $($or "pivoting"$)$ to see different summaries of the source data.

Filtering, sorting, grouping, and conditionally formatting the most useful and interesting subset of data enabling you to focus on just the information you want.

Presenting concise, attractive, and annotated online or printed reports.
