removing data
Hi all,
I need your help! I have a column of data that goes up, down, up, down... and finally increases to a maximum. I need to remove the up and down portion to keep only the final increase... Any ideas how to do that? Thanks |

removing data
This is not a very simple problem. The issue is defining the last minimum.
It depends on your data when and how to define the lat minimum. Can you help? "Lucile" wrote: Hi all, I need your help!

removing data
Here we start at the bottom of a column and work upward. We check that the
data is increasing (moving downwards). When we find the breakpoint, we delete all cells above the point. Sub lucile() n = Cells(Rows.Count, "A").End(xlUp).Row v = Cells(n, "A").Value For i = n - 1 To 1 Step -1 If v < Cells(i, "A").Value Then Exit For Else v = Cells(i, "A").Value End If Next Range("A1:A" & i).Delete Shift:=xlUp End Sub -- Gary''s Student - gsnu200823 "Lucile" wrote: Hi all, I need your help!

removing data
It was what I was thinking. Finding the last minimum is the best option. But
how do you find it!? Because it is not the minimum of the columns. What else do you need to know? "Joel" wrote: This is not a very simple problem. The issue is defining the last minimum.

Tightening up your code just a little bit...
Sub lucile() Set R = Cells(Rows.Count, "A").End(xlUp) For i = R.Row - 1 To 1 Step -1 If Cells(i, "A").Offset(1).Value < Cells(i, "A").Value Then Exit For Next Range("A1:A" & i).Delete Shift:=xlUp End Sub -- Rick (MVP - Excel) "Gary''s Student" wrote in message ...
