I teach adding together data from several worksheets or workbooks using the SUM function or by the use of Data – Consolidate. Yet another way of doing this is to use the PivotTable and PivotChart Wizard. However, if you are using Excel 2007 or Excel 2010, this will not be obvious. Go to the Quick Access Toolbar drop down and click More Commands From the dropdown that says Popular Commands, select Commands not in the Ribbon, find PivotTable and PivotChart Wizard and click Add. Click OK. The PivotTable and PivotChart Wizard button will now be shown on the Quick Access Toolbar.
Click on the button. The Pivot Table and Pivot Chart Wizard opens.
Select Multiple consolidation ranges, then click Next.
If you need to be able to filter the data by more than one field, select I will create the page fields, otherwise leave it at Create a single page field for me, then click Next.
In the Range box, select the first range (including labels) to be included in your consolidated pivot table and click Add. Continue until you have added all required data ranges, then click Next.
Select where you want your PivotTable placed, then click Finish. Your data will be consolidated into one pivottable.
