Combine Duplicate Rows

In Excel, there is often a need to combine duplicate rows in a range and sum them in a separate column. For example, if you have sales by product in a sheet (as shown below), you may want to summarize sales for every product. In the following example, you have products in Column B (including duplicates), and their sales amounts in Column C.

You can combine the data and get a total sales amount for every product in a separate range, next to the original one.

1. Select a cell where you want to get a new data range (e.g., E1), and in the Ribbon, go to Data > Consolidate.
