Excel formula if any cell in a range has a value get the value of another cell

Question

I have the following table

     A   B
1    3   Val1
2    2   Val2
3    2   Val3
4    1   Val1
5    5   Val3

Can anybody help me with a formula to sum cell values from the A column grouped by values of the B column

So it should return Val1 = 4 another formula for Val=2 another for Val3 =7

I Have the following but it is very ugly:

=IF(B1="Val1";A1)+IF(B2="Val1";A2)+IF(B3="Val1";A3)+IF(B4="Val1";A4)+IF(B5="Val1";A5)

Answer 1

您可以按以下方式使用SUMIF ：

=SUMIF(B:B;"Val1";A:A)

Answer 2

可以对每个Valx使用以下公式：

=SUMIF(B1:B5,"Val1",A1:A5)
