Learn how to remove duplicates with Excel
Select the range where you want to remove duplicate values.
A minimum of two cells needs to have values.
Excel will automatically include related cells.
This helps so that you do not break the relationship between the cells.
Find the button under the Data tab in the ribbon.
Start the command by pressing the button.
Select one or more columns that have values.
Press the "OK" button once you have selected the columns.
When the columns have been selected, and you have pressed the "OK" button, the duplicates have been removed.
In this example, we will remove the duplicates for Column B (Age).
Select Column B (Age):
Press the "OK" button...
1 duplicate value was removed.
3 unique values remain.
Tip: Use the Remove Duplicate function with care for large data sets.
If used wrong, it might remove useful data.
