How to Identify Duplicate Entries in Excel Columns?

Duplicate entries can be a hassle to deal with in Excel. Whether it’s a typo or a mistake in data entry, finding and removing these entries can be a time consuming task. Fortunately, Excel offers a range of methods to quickly identify, select and delete duplicate entries in a column.

The most basic approach to finding duplicate entries is to sort the column in ascending or descending order, and then manually scan the list for duplicates. This method is effective, but it can be time consuming if you have a long list of entries.

To use this feature, simply select the column you wish to scan, click the “Data” tab, then click “Remove Duplicates”.

This formula will return the number of times the given value appears in the selected column.

Another popular formula is the COUNTIFS function, which will count the number of times a given value appears in multiple columns.

This formula will return the number of times the given value appears in the selected columns.
