  • Value if false.

How do you use multiple IF statements in Google Sheets?

You can use a nested IF statement as the “value_if_true” argument in the same way. To do this, type =IF(first_test, IF(second_test, value_if_true, value_if_false), value_if_false) . As an example, if cell B3 contains the number 3, and if cell C3 contains the number 4, return a 5.
