Is there some special trick to selecting those cells that are highlighted? 'select cells by format' perhaps? As soon as I selected one of the duplicates, all of the highlights disappeared.
For example, if I have:
dog
doG
dog
I want a feature where it only removes "dog", but not the one with the upper case. Does Kutools have such feature?
Thanks.
Thanks for your feedback. We will try to enhance our feature in upcoming versions.
Do I do something wrong or don't I have the correct version for test?
