I'd appreciate it a lot if someone could help me.
I have two columns (A and B) with values and I want to get a column C with expected results as following:
A | B | C
1 | English | English, French, Spanish
1 | French | (empty)
1 | French | (empty)
1 | Spanish | (empty)
2 | English | English
3 | Spanish | Spanish, Russian
3 | Russian | (empty)
Please note that, even if there are two "French" values in column B for a A column values=1, I need only one results - no duplicates.
I can get result for C3,4,5=(empty) and for C2=English, French, French, Spanish, but don't know how to get rid of duplicate "French, " at least afterward.
Thank you in advance.
