Quickly highlight which entries in your data set are duplicates. If you suffer from deletion anxiety, this is the far better option!

The Problem

So when working with large data sets it’s a common occurrence to have duplicate entries. Often we would like to weed these out! Our first port of call would be to use the in-built Excel function ‘Remove Duplicates’ (Click Here For More Info), however, what if we first want to VISUALLY see which entries are duplicates instead of just having excel delete them. We can use some VBA and some clever error handling to ‘Find’ duplicates and color them RED.

The Code

The code above currently looks at the data from cell A2 downwards. If you wish to search through a different column make sure you change the column reference on Line 9. So now that you can see the offending entries, what if you also want to quickly delete them?

If you want the option to also delete those pesky duplicate rows, we can introduce a small code edit as shown below.

Now sit back and enjoy your clean duplicate free workbook. Maybe hold a small ceremony in the office to mark the occasion!
