Google Sheets – How to Count Occurrences of ‘STRING’ in a Row Starting with ‘IFTEXT’

formulasgoogle sheets

I have a sheet with employee time logs, as follows:

Name    Day1       Day2       Subtotal of 'OFF' days this period
Jess    PRESENT    OFF        1
Bob     PRESENT    PRESENT    0
Name    Day3       Day4       Subtotal of 'OFF' days this period
Jess    PRESENT    PRESENT    0
Bob     OFF        OFF        2

I need to create an automatic total of the number of days off each employee has had. How could I do this? =COUNTIF(1:100,"OFF") would return the total number of off days, but is there a way to get this total only rows where the first cell contains "Jess"?

(In this example, "OFF" is "STRING" in my question, while "Jess" is "IFTEXT")

Best Answer

If you don't want to precalculate the subtotal of off days, you can use an array formula:

=arrayformula(SUM((A:A="Jess")*(B:C="OFF")*1))

A:A="Jess" returns a bunch of TRUE and FALSE, in your sample, it would be {TRUE, FALSE, FALSE, TRUE, FALSE}

B:C="OFF" returns another bunch of TRUE and FALSE, in your sample, it would be {FALSE, TRUE; FALSE, FALSE; FALSE, FALSE; FALSE, FALSE; FALSE, FALSE} (note semicolons denoting the different rows)

And those two multiplied is evaluated as:

From A:A="Jess"  From B:C="OFF"   Result
TRUE             (FALSE, TRUE ) = FALSE TRUE
FALSE            (FALSE, FALSE) = FALSE FALSE
FALSE            (FALSE, FALSE) = FALSE FALSE
TRUE             (FALSE, FALSE) = FALSE FALSE
FALSE            (TRUE , TRUE ) = FALSE FALSE

Only a TRUE multiplied by another TRUE gives a result of TRUE. The *1 last converts every TRUE to 1. SUM then adds all the 1 together.
