This script highlights duplicate values in red. To use it, select a range of cells, run the script, and review the highlighted duplicates.
The COUNTIF function checks the frequency of a value within a range and returns the count. If the count is greater than 1, the value is a duplicate.
If you want to identify unique values instead, Conditional Formatting can also be customized to highlight non-duplicates.
Large datasets can be overwhelming, but the right approach can make all the difference:
Unless you have a backup or use Undo (Ctrl + Z), recovering deleted duplicates can be challenging.

When working with datasets involving multiple columns, identifying duplicates can be more complex. For example, you may want to check for duplicate records based on a combination of first and last names or product IDs and order numbers.
Mastering how to check duplicates in Excel is a crucial skill for anyone working with data. Whether you're using built-in tools like Conditional Formatting and Remove Duplicates, advanced methods like formulas and VBA, or external tools, Excel offers a range of options to suit your needs. By following the tips and best practices outlined in this guide, you can maintain clean, accurate datasets and make better-informed decisions.

Duplicates in Excel refer to identical or nearly identical records within a dataset. They can occur in single columns or across multiple columns, depending on how the data is structured. For instance, if you have a customer list, a duplicate might be two rows with the same name and email address. However, even minor discrepancies in data—like a trailing space or a different case—might cause Excel to treat records as unique.
Duplicates can occur due to various reasons such as manual data entry, importing data from external sources, or merging datasets. These repetitions can lead to inaccurate results in analyses, reporting, and decision-making processes.
