Hello Anne, 

While this would be technically possible, it would probably be relatively 
heavy in terms of performance if we have to support that for any field (or 
all). 

Alternatively, I would suggest that you address this with plain formulas, 
e.g., assuming A1 is the cell that you want to deduplicate, have a new 
column B added with, in B1, the following formula that you can then drag 
down for all your rows: 

=join("||",transpose(unique(transpose(split(A1,"||")))))

(just replace A1 in there with whatever works for you). 

I hope this will do the trick for you. 

Best regards,
Benoît
