Formula to remove duplicates and return a certain cell's text if duplicates found

Will you please attach a SMALL sample Excel workbook (10-20 rows of data is usually enough)? However, please give us an indication of the approximate number of rows of data you want the solution to work with (100, 1000, 100,000 or whatever). Please don't attach a picture of an Excel sheet (no-one will want to re-type all your stuff before starting).

1. It does NOT have to be your real sheet - mock up a SAMPLE if you need to. But not 1000's of rows!!! It makes manual checking so tedious. Whatever you do... make sure that all confidential information is removed first!!

2. Make sure that your sample data are truly REPRESENTATIVE of your real data. The use of unrepresentative data is very frustrating and can lead to long delays in reaching a solution.

3. Make sure that your desired solution is also shown (mock up the results manually).

4. Try to avoid using merged cells. They cause lots of problems!

Unfortunately the attachment icon doesn't work at the moment. So, to attach an Excel file you have to do the following: Just before posting, scroll down to Go Advanced and then scroll down to Manage Attachments. Now follow the instructions at the top of that screen.

Hi Formulae can't remove data, you'd need VBA to do that.

However you can identofy duplicates by using the MATCH() function and once you've auto filtered the data using the column with the match function you can delete/copy/paste the rows as you wish and then remove the autofilter

In B2, copied down:

=IF(COUNTIF(A:A,A2)>1,A2,"N/A")

You may need ; instead of ,

You're welcome.
