Intersect Function in Excel

The term Intersect refers to apply a SUM Function to only those cells which are intersecting.

To have a better understanding of the concept, follow the steps below:

1. For this example, consider a scenario that there are 2 sets of values that are needed to be added collectively. However, their physical position on MS Excel sheet is distant. Each set carries 9 values in a 3 x 3 cell formation as shown in the figure below:

2. Now, in order to sum up only the overlapping values at one place, enter the SUM function having Cell range of Set 1 and Cell range of Set 2, both separated by a space.

3. The output would be the sum of only 2 cells which are common in both ranges

The above output is sum of only two cells which are common in both value sets (highlighted in green color)
