Using Conditional Formatting
Conditional formatting is a feature in Excel that allows you to automatically apply specific formatting to cells that meet certain conditions. In this case, we can use it to highlight duplicate values in a dataset. To use conditional formatting, select the range of cells you want to check for duplicates. Then, go to the Home tab, click on Conditional Formatting, select Highlight Cells Rules, and then Duplicate Values. Excel will automatically highlight all the duplicate values in the selected range.

Using the COUNTIF Function
The COUNTIF function in Excel counts the number of cells within a range that meet a single condition. This function can be used to identify duplicates in a dataset. To use the COUNTIF function, you need to enter it in a cell with the range and criteria as arguments. The range is the group of cells you want to check for duplicates, and the criteria are the condition that defines what you consider a duplicate. If the result of the COUNTIF function is more than 1, it indicates that the value is a duplicate.

Using the Remove Duplicates Feature
Excel has a built-in feature to remove duplicates directly. This feature is handy to eliminate duplicates from your dataset entirely. To use this feature, select the range of cells or the entire table where you want to remove duplicates. Then, go to the Data tab and click on Remove Duplicates. Excel will automatically remove all the duplicate values in the selected range.

Using Pivot Tables
PivotTables is a powerful tool in Excel that allows you to summarize and analyze large datasets. You can also use PivotTables to identify duplicates in your data. To use Pivot Tables to find duplicates, create a Pivot Table with the data you want to check. Then, add the same field to the Rows and Values area of the Pivot Table. If any value appears more than once in the Values area, it indicates that it’s a duplicate.
