I have an XLS file with a column A containing many name entries. It looks somewaht similar to the following:
I am looking for a way to dynamically create a list in column B of the first 25 unique entries in column A, and to do so in alphabetic order.
The result is supposed to look somewhat like this:
Of course I could just filter/sort/delete duplicates, but column A is subject to frequent updates and I need to keep manual steps to a bare minimum.
In a sense, I am looking for a function similar to Google Sheet's unique. Hence my question relates to others asked e.g. here and here.
