Array Function vs Countif and Countifs

by | Aug 28, 2017

If you want to become a master of Excel, you need to learn how to use array formulas. Array formulas will perform calculations that other formulas in Excel can’t do.

Here is example 1 – multi-cell calculation to return multi results

  1. Select D2 to D8.
  2. Type =B2:B8*C2:C8.
  3. Press Ctrl + Shift + Enter on the keyboard.
  4. Click in cell D2 and look at your formula bar.

Array function - multi results in multi cells

An array function will have braces { } around it. You can not manually type the braces. You must use Ctrl + Shift + Enter.

Here is example 2 – multi-cell calculation to return one result

Using the same example from above, I want to know what is the grand total.

  1. Click in cell C10.
  2. Type =SUM(B2:B8*C2:C8).
  3. Press Ctrl + Shift + Enter on the keyboard.
  4. Click in C10 and look in the formula bar.
