Textsplit passed to unique

[gryzbert]

Hi, I am trying to find unique values from a list where entries can consist of multiple values that are separated by slashes. The Textsplit function splits but omisses text after the first separator. 

I want the output

a

b

List		Sort/Unique/Textsplit for the array = SORT( UNIQUE( TEXTSPLIT( D3:D4, "/",,TRUE,0)))	Textsplit for each row
a		a	a
a/b			a	b

How can I get there?

Thanks for your help.

Simplest option is to join the strings first, prior to splitting:

=SORT(UNIQUE(TEXTSPLIT(TEXTJOIN("/", , D3:D4), , "/", TRUE, 0)))

Works like a charm! Thanks a lot! :)

=SORT(UNIQUE(TEXTTEILEN(TEXTJOIN("/",TRUE,A1:A2),"/"),TRUE))

EDIT:  Not fast enough.
