Article 10 - Intersection Operator in Excel

Today, I am going to talk about a nifty but not so well known feature of Excel. This is about Intersection Operator in Excel. Before, I go deep in Intersection Operator, I would like to talk about Reference Operators in Excel. There are 3 Reference Operators -

1. Range Operator (represented by Colon) - It specifies a range. Hence, A1:B10 where a colon (:) has been used, specifies all cells contained between A1 to B10. Similarly, D:D specifies entire column D. 3:3 specifies entire row 3.

2. Union Operator (represented by Comma) - It specifies the union of ranges. Union means inclusive of all cells in the ranges specified. Hence, if you specify A1:A5,D2:D4 it will include all cells lying between A1 to A5 and D2 to D4. Hence, if I specify =SUM(A1:A5,D2:D4)
The answer would be 221.
If I specify =SUM(A1:A5,B2,D2:D4,C4,C1:C2), it will pick up all cells from A1 to A5, B2, D2 to D4, C4 and C1 to C2.
The answer would be 326.
