Hello,

So I wanted to filter out the start and end time from a list of dates and values. I was able to create a new column to just show a date when the value is >0. =IF(B1>0,A1,"").

But i would like to be able to create another table of just start and end time from the list from D. skipping anything in the middle and stopping when it hits a blank cell.

like so. (manual input)

I tried using =LET(f,FILTER(A2:200,B2:B200>0),INDEX(f,SEQUENCE(ROWS(f)/2,,,2)+{0,1})) but it only give me increments of 15 minutes.

like this which i don't want.

Any ideas?

Hello, I am not sure whether the following is what you are looking for and whether it will work but it is a trial and error:

Excel Formula: 
=LET(
times,A1:A31,
a,B1:B31,
b,SCAN(0,a=0,LAMBDA(x,y,x+y)),
c,IF(a=0,"",b),
DROP(REDUCE("",UNIQUE(FILTER(c,ISNUMBER(c))),LAMBDA(x,y,VSTACK(x,HSTACK(MIN(FILTER(times,c=y)),MAX(FILTER(times,c=y)))))),1))

That.. worked.. amazingly... i have so much to learn.

I know it is a lot to ask, but would you mind schooling me on how you came about creating this formula? I have been wracking my mind for 3 hours before asking my question on this forum on how to create a formula.

Please and thank you!

Welcome to the MrExcel board!

Does this considerably shorter (& perhaps easier to understand?) one also do what you want?

.. or maybe just as two separate filter formulas?
