Create a PivotTable in Excel - Microsoft Support

Try it!

A PivotTable is a powerful tool to calculate, summarize, and analyze data that lets you see comparisons, patterns, and trends in your data.

Select the cells you want to create a PivotTable from.

Note: Your data shouldn't have any empty rows or columns. It must have only a single-row heading.
Select Insert > PivotTable.
Under Choose the data that you want to analyze, select Select a table or range.
In Table/Range, verify the cell range.
Under Choose where you want the PivotTable report to be placed, select New worksheet to place the PivotTable in a new worksheet or Existing worksheet and then select the location you want the PivotTable to appear.
Select OK.

To add a field to your PivotTable, select the field name checkbox in the PivotTables Fields pane.

Note: Selected fields are added to their default areas: non-numeric fields are added to Rows, date and time hierarchies are added to Columns, and numeric fields are added to Values.
To move a field from one area to another, drag the field to the target area.
