A simple trick in Excel allows you to remove duplicate values from a column in Excel. Depending on your version of Excel, yours may look a bit differently but the process is nearly the same. Below, I’m using Excel 2016.
1. Select the column, or the values from which you’re removing duplicates.
Note: You could also just start with step 2, and then select the relevant column(s) from the resulting dialog.
2. Go to Data > Remove duplicates (in the Data Tools panel)
3. Confirm if your column has a header (column title or not) and click OK.
4. Excel will confirm the number of duplicates found and how many remain. Click OK.
Fun Fact: It leaves the first instance of any duplicates.
