Conditional Formatting

Use When:

  • You have a data set that is small enough to be cleansed visually
  • You want to visually identify, analyze, and confirm your duplicates before removing them
  • Your data is complex enough that highlighting of duplicates will help identify them

One of the most useful conditional formatting functions in Excel is the ability to highlight duplicate values.  To use this function, simply highlight the data in question.  Within our sample data set, since we are only concerned about duplicate values in the Unique ID field, we’ll highlight that specific column.  Then under the “Home” tab of the Excel ribbon, click:

  • Conditional Formatting
  • Highlight Cell Rules
  • Duplicate Values

If you use the default setting, your cells will be highlighted in red.  Since conditional formatting doesn’t automatically remove duplicates for you, you’ll have to manually delete them.  Because of this limitation, the conditional formatting approach is primarily useful for smaller data sets, where you can reasonably scan through the entire data set to make edits.

Sort the Data

Use When:

  • You have a data set that is small enough to be cleansed visually
  • You want to visually identify, analyze, and confirm your duplicates before removing them
  • Your data is simple enough that you can easily tell the values apart

Sorting your data table is one of the fastest ways to find duplicates in Excel.  Assuming your data set is small and has simple values, a simple sort should allow you to see if any duplicates exist.

However, if you have complex values in your column, such as a ten digit alpha numeric code, it’ll be very difficult for you to see the repeating values visually.  In that case, you should use conditional formatting.

To sort the data, go to the “Data” tab of the Excel ribbon and click any one of the sort buttons.
