#1 – Remove Duplicates From Data Tools Group
Suppose we have data in our sheet as below.
We want to check how many people’s names are mentioned in column B. We can count the number of unique names for a smaller amount of data. But it may take a while to figure out the same for a larger amount of data. It is where removing duplicates in Excel comes in handy.
- Select column B. In the “Data” tab, under the “Data Tools” section, click on “Remove Duplicates.”
- A dialog box appears. It asks if we want to remove duplicates from the current selection or if we want to expand our selection. As column A has just one type of data, and we need to remove duplicates from column B, we will select “Continue with the current selection.”
- After selecting, “Continue with the current selection,” click on “Remove Duplicates,” another dialog box appears.
- It tells us to select the column from which we want to remove duplicates. If we had chosen the whole data, it would show all the columns, and it is up to us to determine the column from which we want to remove duplicates.
- As column B is selected, we click on “OK,” and Excel prompts us that the duplicated data has been deleted and only the unique values remain.
- We can see that the duplicate data has been deleted from column B, and only the unique values remain.
The above method was the first method of removing duplicates.
#2 – Using Advanced Filter In Excel
Now, we will try to remove duplicate data from the “advanced filterAdvanced FilterThe advanced filter is different from the auto filter in Excel. This feature is not like a button that one can use with a single click of the mouse. To use an advanced filter, we have to define criteria for the auto filter and then click on the “Data” tab.

Let us consider the same data in sheet 2 and try to delete the duplicate data using the second method.
The data is the same as below,
- Step 1 – Under the same “Data” tab, in the “Sort & Filter” section, click on “Advanced Filters.” A dialog box appears.
- Step 2 – Select “Copy to another location.”
- Step 3 – We need to provide the data range to the advanced filter so we can select our data in the sheet.
- Step 4 – In the “Copy to:” box, we must give a location where the data needs to copy. For the current scenario, we will choose a location in the current sheet. We can choose any other sheet also.
- Step 5 – Now, select “Unique records only,” as it will filter out the duplicate data and paste only the unique data to the new destination.
- Step 6 – When we click on “OK,” we can see that the data has been pasted to the destination. However, there are no duplicate values.
The above method was the second method of removing duplicates using the advanced filter tool.
