First, select the range of cells in your spreadsheet where you want to locate duplicates. Navigate to the ‘Home’ tab, and within the ‘Styles’ group, click on ‘Conditional Formatting.’ Then, choose ‘Highlight Cells Rules’ and opt for ‘Duplicate Values.’ A dialog box will appear, allowing you to select the formatting style for highlighting the duplicates. Once you’ve made your choice, click ‘OK.’
Now, Excel will instantly highlight the duplicate values within your chosen range, providing a visual aid for easy identification and organization of your data.

Using the ‘Remove Duplicates’ Feature
To efficiently locate and eliminate duplicates in Microsoft Excel, start by selecting the range of cells in your spreadsheet where you want to perform this action. Next, navigate to the ‘Data’ tab and click on ‘Remove Duplicates’ within the ‘Data Tools’ group. In the ensuing dialog box, choose the specific columns you want to check for duplicates and click ‘OK.’ Excel will then proceed to remove the identified duplicates and present a message detailing the number of duplicates successfully removed, along with the count of unique values that remain in your dataset.

COUNTIF Formula
Utilizing the COUNTIF formula in Microsoft Excel provides a straightforward method for identifying duplicates within a dataset. To employ this formula, begin by selecting a cell adjacent to the range where you intend to find duplicates. Then, input the formula ‘=COUNTIF(range, cell),’ replacing ‘range’ with the actual range of cells you want to check for duplicates and ‘cell’ with the specific cell containing the value to be evaluated.
Press Enter to apply the formula, and Excel will swiftly calculate the count. If the result is greater than one, it indicates the presence of duplicates in the specified range.

IF and COUNTIF Formula
Employing the combination of the IF and COUNTIF formulas in Microsoft Excel allows for the effective identification and marking of duplicates with a designated text, such as ‘Duplicate.’ To implement this approach, start by selecting a cell adjacent to the range where you wish to locate duplicates. Subsequently, input the formula ‘=IF(COUNTIF(range, cell)>1, “Duplicate”, “”)’, adjusting ‘range’ to signify the range of cells under examination and ‘cell’ to denote the specific cell holding the value for assessment.
Press Enter to apply the formula, and Excel will execute the logic: if the count of the value exceeds one in the specified range, it will label the duplicate with the chosen text; otherwise, it will remain blank.
