In a previous article "Automatically filter unique row records from multiple columns", i presented a solution to filter out unique values from several columns. In this article i want to show you how to narrow that search down a bit further. This time i want to search for unique values with a singel column criteria that must match.

I want to search for unique distinct values with column B only containing value "A"

Array formula in G2:

=INDEX($A$2:$D$25, MATCH(0, IF($B$2:$B$25="A", COUNTIF($G$1:$G1, $A$2:$A$25)*COUNTIF($H$1:$H1, $B$2:$B$25)*COUNTIF($I$1:$I1, $C$2:$C$25)*COUNTIF($J$1:$J1, $D$2:$D$25)), 0), COLUMN(A:A)) + CTRL + SHIFT + ENTER copied to the right to J2 and then copied down as far as needed.

See picture below.
