In this article, we’ll show you how to filter out duplicates in Excel and ensure that your data is accurate and up-to-date.

How to Filter Out Duplicates in Excel?

Understanding Duplicates in Excel

Duplicates in Excel are entries that appear more than once in the same data set. This can be a huge problem for users who rely on accurate data. Excel does not have a built-in feature to filter out duplicates, but there are several methods that can be used to identify and remove them.

The first step in filtering out duplicates in Excel is to identify which entries are duplicates. To do this, users can either use a built-in function or manually compare entries. The built-in function is the COUNTIFS() function, which will count the number of occurrences of a given entry. If the count is greater than one, then the entry is a duplicate. Another option is to manually compare entries and look for any that appear more than once.

Using the Filter Feature in Excel

Once the duplicates have been identified, they can be removed using the filter feature in Excel. To do this, users should select the data set they want to filter and click the “Data” tab on the ribbon. Then, they should click the “Filter” button and select the “Unique Records Only” option. This will filter out any entries that appear more than once in the data set.

Using the Advanced Filter Feature in Excel

The advanced filter feature in Excel can also be used to filter out duplicates. To use this feature, users should select the data set they want to filter and click the “Data” tab on the ribbon. Then, they should click the “Advanced” button and check the “Unique Records Only” box. This will identify and remove any entries that appear more than once in the data set.

Using Conditional Formatting in Excel

Another method for filtering out duplicates in Excel is to use conditional formatting. To do this, users should select the data set they want to filter and click the “Home” tab on the ribbon. Then, they should click the “Conditional Formatting” button and select the “Highlight Cells Rules” option. This will bring up a list of options for conditional formatting. Users should select the “Duplicate Values” option and then click the “OK” button. This will highlight any entries that appear more than once in the data set.

Using the Remove Duplicates Feature

The “Remove Duplicates” feature in Excel can also be used to filter out duplicates. To use this feature, users should select the data set they want to filter and click the “Data” tab on the ribbon. Then, they should click the “Remove Duplicates” button and select the columns they want to filter. This will identify and remove any entries that appear more than once in the data set.

Using the VLOOKUP Function

The VLOOKUP function in Excel can also be used to filter out duplicates. To use this feature, users should select the data set they want to filter and click the “Formulas” tab on the ribbon. Then, they should enter the following formula:

=VLOOKUP(A1,A:A,1,FALSE)

This formula will search the data set for any duplicate entries and return the first occurrence of the entry. This can then be used to identify and remove any entries that appear more than once in the data set.
