The simplest solution to remove duplicate entries in Excel works as follows:
- Go to “Data” in the register menu
- Mark the table in which duplicate entries are to be deleted
- Click Remove Duplicates
- Confirm with OK
Now it could happen that you get the error message that no duplicate entries were found. And that although you can even see them with your own eyes in the table. We deliberately included a few duplicate entries in our example table, but not all values within the individual rows are exactly the same with another row within the selected table. With this general method, it does not work error-free.
If you go to “Duplicate Entries” you will be shown the columns within which to search for duplicates in a dialog window, and you can mark them or exclude them from the selection within which you should search for duplicates. Now if we only include column C
in the selection it works immediately and our duplicate entries are found and the affected rows are also removed. But here, too, an error can ultimately creep in again if there is a duplicate entry in another column, it would not be found when searching for duplicate entries within only one column.
