Hello,

I am trying to make a formula that can detect consecutive duplicate values in excel. Once this is detected I want it to only return the lowest value for "LOW" and highest values for "HIGH".
Any way this is possible to do with helper colums and formulas?

In the data below I have shown how I want the data to turn out.

Easy bullets in Excel
If you have a numeric keypad, press Alt+7 on numeric keypad to type a bullet in Excel.
E1 is a array formula (in 2021, you don't have to add CTRL+Shift+Enter), so the cells around must be empty otherwise you get a "overloop error"

Solution
Why is the 2.62 in row 11 marked as a LOW? The value in row 10 is lower so should row 11 not be HIGH?

Your helper formula for column D. Paste the formula into cel D3 and copy it down.
VBA Code:
=IF(OR(AND($B3="HIGH",$B4="HIGH"),AND($B3="LOW",$B4="LOW")),$D2,$D2+1)

And the formula for cell E3. This formula can then be dragged into the other columns and rows.
VBA Code:
=INDEX(A:A;MATCH(ROW()-2;$D:$D;0);1)

Nevermind, i'm just stupid. My excel only works with "," instead of ";". But yeah, you are correct I meant to mark 2.53 as LOW instead of 2.62. Any way to make formula work with that? Thank for help!

Does this work if I want 2.53 as LOW instead of 2.62? I mistyped in my post..

perhaps this is better, bit it'll not be an answer to your bigger question to find the ultimate top or bottom in a longer range. I think you need VBA with adjustable parameters to do so, but i can't remember why that wasn't allowed, was it a Mac ?
