I know that this is an easy formula using index but i can't quite get the syntax. I am looking to return the header after finding the smallest value in a range. I am using =index(c3:e3,match(min(c4:e25),c4:e25,0)) and getting NA.
=CONCAT(IF(C4:E25=MIN(C4:E25),C3:E3,""))
=TEXTJOIN(", ",1,UNIQUE(IF(C4:E25=MIN(C4:E25),C3:E3,"")))
Thanks Peter. Very helpful.If there will definitely only be one cell in C4:E25 that is the minimum value in that range then try
Excel Formula:=CONCAT(IF(C4:E25=MIN(C4:E25),C3:E3,""))
If multiple cells could hold equal minimum values then try
Excel Formula:=TEXTJOIN(", ",1,UNIQUE(IF(C4:E25=MIN(C4:E25),C3:E3,"")))
