The least likely task to be done while the worksheets are grouped when you have a workbook that contains sales data for different regional sales representatives of a company, is to make sure that you ungrouped sheets if ever you want to perform a task on only one worksheet because if you forget to ungroup sheets you could potentially ruin several worksheets by overwriting data on all worksheets instead of just the active worksheet.
