Remove duplicates not working.. Can't create relationship

The solution that has worked for me:

in the query editor, select your column that you want to be unique and then:

1) Click on the "Transform" tab in the ribbon, click on the "Format" button, and then select "UPPERCASE" or "lowercase"

2) make sure the column is still selected, then click on the "Home" Tab, and then click on the "Remove rows" button, then select "Remove Blank Rows"

3) make sure the column is still selected, then click on the "Home" Tab, and then click on the "Remove rows" button, then select "Remove Errors"

4) Finally, click on Remove Duplicates button.

So far, these steps have always worked for me!

I am getting this issue with the latest version of Desktop as well. My dataset is 4,700 rows of data. Remove Duplicates is applied in the query stage, but when the data is loaded into the data model there are duplicates in the data.

I cannot manually search for the duplicate values in the query because it says 'Limit of 1000 values reached'.

Create a table and then export data to excel and do a duplicate check there.

I don't need to check duplicates, I need the query to filter them out properly so I can create a many-to-one relationship that doesn't return an error and mess up the scheduled refresh every time another duplicate is entered on the list.

What if it's a concatenated calculated column which you can't see in Power Query Editor?
