Hi everyone,

I have some very basic scripting skills but they don't yet translate well to VBA so would very much appreciate the benefit of your knowledge.

I have a spreadsheet with over 6k rows, each with over 30 columns.

My focus is in 2 columns. ColumnA is formatted as General, ColumnB as Number.


[TABLE="class: grid, width: 425"]
<tbody>[TR]
[TD]ColumnA[/TD]
[TD]ColumnB[/TD]
[/TR]
[TR]
[TD]05255088-0f15-48f1-a65e-affb6d583d35[/TD]
[TD="align: right"]1373064224475[/TD]

I need your assistance with VBA code that will Fill the cell in ColumnB if it changes within the same ColumnA data.


So the output would end up like this. (Although the cell would be filled, not the text turned red)

[TABLE="class: grid, width: 425"]
<tbody>[TR]
[TD]05255088-0f15-48f1-a65e-affb6d583d35[/TD]

So it's pretty basic. If we simply remember the first ColumnA and ColumnB data, go to the next row, if ColumnA is the same, then ColumnB should be the same. If it's not, then fill with red, go to the next row, repeat. if ColumnA changes, remember the new pair, go to the next row and compare again.


I've thought about this from a scripting perspective, and imagine that something like this would do the job:

Code:
sub FindBadTermID ()
     Dim row As Integer
     Dim dataA as string, dataB as string
     Set row = 2

     newColumnALoop
          Set dataA = A(row), dataB=B(row)                         # Get the first pair in a new ColumnA group
          Set row=row+1
               testColunBLoop
                  if A(row) = Blank, end
                  if A(row) != dataA, goto newColumnALoop     # If it's a new ColumnA group, go back and get first pair
                  if B(row) != dataB, fill B(row)=red                # If ColumnB is different that ColumnB of the first pair, make the cell red
                  Set row=row+1
                  goto testColumnBLoop
   
End Sub


I've gotten a start on changing the script to VBA, but am now strugging. Would you please take a look and give me your thoughts and code suggestions?

Thank you very much!

Which Excel functions can ignore hidden rows?
The SUBTOTAL and AGGREGATE functions ignore hidden rows. AGGREGATE can also exclude error cells and more.
3gswish,

There is a lot of good information in the list.

You are very welcome. Glad I could help again.
