One of the great features with Pivot Tables is the ability to create multiple pivot tables in separate sheet by summarising by one of the report fields. For Excel 2011 on a Apple, one way to find it is by 2 finger clicking the report field.
The option at the very bottom will be ‘Show Report Filter pages’. Click on this and then choose which report field to use. Excel will then create a new pivot for each unique item in the report field.
