How to Get Rid of Duplicates Excel

Duplicate data in excel can be an issue that makes the value of our data worse. For instance, mastering how to filter data becomes more difficult when we have many duplicates in that. Moreover, it increases the chances of errors in your analysis, and ultimately, it could give you biased results. Nobody wants to spend hours on Excel to find duplicates and delete them manually. Fortunately, Microsoft Excel offers several efficient and straightforward methods to eliminate duplicates. In this post, we’ll explore some practical ways of getting rid of duplicates in Excel, making your spreadsheet more accurate and easier to manage.

Method 1: Remove duplicates using Excel’s built-in tools

The most straightforward way of getting rid of duplicates in excel is using the built-in Excel tools. Follow these simple steps:

Step 1: Select the range of cells

To remove duplicates, you need to specify the range of cells that you want to check for duplicates. Click on any cell in the range, then highlight the cells you want to include.

Step 2: Open the Remove Duplicates dialog box

Click on the “Data” tab in the ribbon menu. In the “Data Tools” group, select “Remove Duplicates.”

Step 3: Choose the columns you want to check for duplicates

Excel may automatically detect the range you want to de-duplicate. If not, you can select, or unselect, columns to include or exclude in your de-duplication efforts.

Step 4: Click OK

After selecting the columns you want to remove duplicates from, click OK to remove duplicates.

Method 2: Use Excel formulas to find and remove duplicates

If you have unique requirements for finding and removing duplicates, you can use Excel formulas. Follow these steps:

Step 1: Identify the target cells

In an empty cell, enter the formula =COUNTIF(range,cell), replacing “range” with the column range where you want to locate the duplicates and “cell” is the first cell in the range. Press enter. The formula will return the total number of cells with the same content.

Step 2: Filter duplicates

Highlight the range and go to the “Data” tab. Click “Filter.” Choose the filter dropdown on the column with the duplicates. In the dropdown, deselect everything and then select “0” (meaning it only shows values that appear once). After applying the filter, you’ll have isolated the duplicates.

Step 3: Remove duplicates

You can highlight the range containing the duplicates and click the “Delete” button or right-click and select “Delete” to get rid of all values that appeared multiple times.

Method 3: Advanced Filtering to remove duplicates

Filtering in advanced mode gives you more power over the selection of unwanted data. Follow these instructions:

Step 1: Set up Advanced Filter

On the “Data” tab, click “Advanced” in the “Sort & Filter” group. This will open the Advanced Filter dialog box.

Step 2: Choose the range to filter

Specify the range of data you want to filter. Make sure to click the “Filter the list, in-place” checkbox.

Step 3: Configure the criterion range

Choose a location to place your advanced filter, and set up a criterion range. The criteria specify which values in the data should be shown based on the specified conditions. Exclude duplicates by using the “Unique records only” checkbox.

Step 4: Apply the filter

Once the criterion range is properly set up, click “OK” to apply the filter.
