Change rows to colums

Hello Anonymous 

the Text.Combine has to be used as pivot-function of your third column. Here an example

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WcjRU0lFyAhHOhkqxOjABI5CAEUTACF2FEbKKWAA=", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [A = _t, B = _t, C = _t]),
    #"Pivoted Column" = Table.Pivot(Source, List.Distinct(Source[B]), "B", "C", each Text.Combine(_,",")
)
in
    #"Pivoted Column"

Copy paste this code to the advanced editor in a new blank query to see how the solution works.
