When you double-click on a pivot table value cell, Excel creates a new sheet, with a list of all the records that make up that total value. The double-click runs Excel’s Show Details command – it’s a helpful troubleshooting feature, but can add clutter to a workbook, because of all the sheets that it creates.
To help you keep things tidy, I created a sample file with macros that label the Show Details sheets when you create them. Then, when the workbook closes, another macro will check for those sheets, and asks if you’d like to delete them. I updated the workbook this week, so take a look, if it’s something you need.
