Finding common AD groups in a list

**JohnPWilliams** · 02-06-2012, 06:12 AM

Hello,

I'm collating some lists of Active Directory (AD) groups which various staff in a department have access to. I will then go through these lists to find which groups are common across all users. I've been doing this manually but this is extremely time consuming and limits the number of staff I can make comparisons across. Is there a way of doing this automatically in Excel (2010)?

Currently, the data is in columns, with staff IDs in row 3 and the list of AD groups in rows 14 - 120.

Any suggestions gratefully received!

Thanks,

John.

To best describe or illustrate your problem you would be better off attaching a dummy workbook, the workbook should contain the same structure and some dummy data of the same type as the type you have in your real workbook - so, if a cell contains numbers & letters in this format abc-123 then that should be reflected in the dummy workbook. Don't upload a picture when you have a workbook question. None of us is inclined to recreate your data. Upload the workbook and manually add an 'after' situation so that we can see what you expect. In addition clearly explain how you get the results..

JPW Sample List.xlsx

TMShucks - thanks for the instructions. Hopefully the sample has attached correctly.

I've had to massively simplify the data as it contained pretty clear references to our company's AD structure. The first is a mock-up of the data as I receive it. The second worksheet demonstrates how I've been high-lighting common entries across the lists. I'd like to do this automatically if at all possible.

Select all the cells from B11 down to the end of the data (in column G) in the example.

Then use the Conditional Format condition: =COUNTIF($B:$G,B11)=COUNTA($B$1:$G$1)

B1 to G1 contain the Staff IDs so the COUNTA($B$1:$G$1) is counting the number of staff.

The COUNTIF($B:$G,B11) is counting how many times the value in B11 (the AD Group) appears in columns $B to $G (all AD Groups across all staff)

If they're the same, this means that the AD group is common to all users.

See the example; you confused me a little because the Finance Groups are in the highlights sheet but not in the sample list.
