Dear T. Valko
I have use your suggested formula and it has proven very efficient if there
is no repeat value in B col. May I ask how to revise your suggested formula
if A and B have the same value of 45?

Many thanks,
Wilson

Try this entered in C3 and copied down:

=INDEX(A$3:A$7,MATCH(SMALL(B$3:B$7,ROWS(C$3:C3)), B$3:B$7,0))

If there are duplicate numbers then a different approach will be needed.

The 2 data sets are assumed running in A3 and in B3 down, viz.:
In A3 down is: A, B, C, D and E
