Find duplicates in columns via conditional colors like in Excel

We use a lot of boards with for example mobile phone numbers. These are unique number however the user can make an error. It would be nice to have an option where we can filter out duplicates of a column. In excel you have a powerful filter to this. Highlight duplicates in a color. I think this would make Monday even more powerful if this could be added. This will lead to less input errors of users when a user enters a value that already is in a column.

Hello @Phils,
The Duplicates and Uniques app can help you with that. You can create a template that will run anytime for example, an item is added or when a status changes. If a duplicate exists, it will make you show a duplicate label.

I have this issue as well, we need a way of finding duplicate entries in any given column, I would prefer a no cost option.
