Is there any query function in google sheets can solved this problem? since index match function only returns one IP value that matched first if there are 2 matched pairs. Thank you

Answer 1

You can first get a data base as follows (in F2)

=sort(split(arrayformula({ A2:A7 &"|seller|" & B2:B7 ; C2:C7 &"|buyer|" & D2:D7}),"|"))

then get unique values in J2

=unique({A2:A7;C2:C7})

and finally search all datas corresponding to unique values

=iferror(join(char(10),,query({$F:$H},"select Col3 where Col2='"& K$1 &"' and Col1='"& $J2 &"' ")))

you have to duplicate that formula
