Normally when we have dirty data, we tend to get a lot of duplicates. But in Excel it is very easy to spot the duplicates for your data cleanup!
Here is our sample list of words, you can see it has a lot of duplicates:
I explain how you can do this below:
STEP 1: Select your list of words / data:
STEP 2: Go to Home > Conditional Formatting > Highlight Cells Rules > Duplicate Values
STEP 3: You can select the formatting that you want. For our example, we selected Green Fill with Dark Green Text.
You will now see the magic happen, all of the duplicate values are now highlighted in your Excel worksheet!
