谷歌表格数组

Question

Column A     Column B    Column C
yes          apple       apple
no           banana      peach
no           pear
yes          peach

(in google sheets)

How to I make a simple array that will output as shown above?

I currently have:

    =if(A1="yes,b1,"")
    =if(A2="yes,b2,"")
    =if(A3="yes,b3,"")
    =if(A4="yes,b4,"")
    

But the output is:

Column A     Column B    Column C
    yes          apple       apple
    no           banana       
    no           pear
    yes          peach       peach

SOLVED!

=FILTER(B1:B4,A1:A4="yes")

Answer 1

You have to filter C column showing only rows where B column contains "Yes"

=filter(C2:C,B2:B="Yes")

Answer 2

=IF(A2 = "yes",B2,"")
