3 Methods To Find Duplicates in Excel Without Deleting Them
Before we start to find and delete duplicates in Excel, our first goal should be to identify them within a dataset. Learning to find duplicates in Excel without deleting them is crucial for maintaining data accuracy and ensuring reliable analysis. Let’s discuss some methods that can help find duplicates in Excel.
Use Conditional Formatting To Find and Delete Duplicates in Excel
Conditional formatting is a handy feature in Excel that allows you to highlight duplicate values visually. This feature lets you find and delete duplicates in Excel effectively. The process of using this feature is straightforward; consider the steps below.

Employ Excel’s built-in Functions COUNTIF and VLOOKUP
Microsoft Excel provides hundreds of built-in functions you can employ to handle specific tasks within your data sets. Despite the various functions set aside for identifying duplicates with a dataset in Excel, the two common ones are COUNTIF and VLOOKUP.
Let’s explore how these two functions work within a large dataset to find and delete duplicates in Excel.
COUNTIF Function: This built-in function allows you to count the occurrence of a specific value within a range. To find duplicates using COUNTIF, insert a new column next to your dataset and enter the formula “=COUNTIF (range, cell).”
Replace “range” with the range of cells you want to check for duplicates. Also, replace “cell” with the cell reference of the value you want to count. Drag the formula down the column to apply it to all the cells. This function will indicate cells with a count more significant than one as a duplicate.
VLOOKUP Function: This built-in function helps you look for a specific value in a range by searching for it vertically across the worksheet in Excel. To use the VLOOKUP function to find duplicates, insert a new column next to your data and enter the formula “=VLOOKUP (cell, range, column, FALSE).
Replace “cell” with the cell reference of the value you want to search. Replace “range” with the range of cells you want to search within. Finally, replace “column” with the column where the duplicates are. When you are through with your input, Click “Enter.”
These two built-in functions are helpful to find and delete duplicates in Excel.
Use the Filter Function
Another helpful technique to find duplicates in Excel without deleting them is using Excel’s filter function. This function allows you to display only the duplicate values with a column. To use the filter function, follow these easy steps below.
- Select the range of cells containing your data.
- Navigate to the Data Tab and click Filter in the Sort & Filter group.
- Open the dropdown menu for the column you want to check for duplicates.
- Uncheck the “Select All” option and scroll down to select “Duplicates.”
- Excel will filter the column to display the duplicate values.
Any of these three techniques can help you quickly find duplicates easily within your dataset on Excel. What can you do if you don’t need the duplicates anymore? Let’s consider how to find and delete duplicates in Excel.

- Afterward, check the “Unique records only” box.
- Click OK to apply the filter and copy only the unique values to the specified location.
Finding and deleting duplicates in Excel is highly efficient when accessing the original data with separate data of unique values.
Use the Excel Formula To Find and Delete Duplicates in Excel
You can use the Excel formula to find and delete duplicates in Excel. One powerful formula you can utilize is the “COUNTIF” duplicates. Here is how to use this Excel formula to delete these duplicates.
- Insert a new column next to the column containing duplicates.
- In the first cell of the new column, input the formula” =IF(COUNTIF (range, cell) > 1, cell).” Replace “range” with the range of cells you want to check for duplicates and “cell” with the cell reference of the value you want to evaluate.
- Drag the formula from the reference cell to all cells in the column.
- Copy and paste the new column as new values over the original column.
- Finally, delete the new column.
While this Excel formula cannot hide duplicates, they effectively remove them in Excel. Overall, using the three methods above helps find and delete Excel duplicates. Thus, they can efficiently clean your datasets and ensure accurate analysis.
How To Find and Delete Duplicates in Excel on Multiple Columns
Several powerful built-in features can help you find and delete duplicates in Excel. While dealing with large datasets, we could face a problem where multiple columns contain duplicates.
Deleting individual duplicate rows can be strenuous and time-consuming. As such, Excel comes to the rescue by offering an advanced feature – Power Query.

- A dialog box will pop up; select “OK.” Excel will begin its work in finding and deleting the duplicates in the datasets.
- Finally, An Excel prompt will notify you of the duplicate values it found and removed and the number of unique values remaining.
Using the Power Query function is a copy of your original worksheet. So, you needn’t worry about removing the duplicates entirely. Alternatively, if you want to keep unique values, follow the steps outlined for the advanced filter option.
