Hi Anonymous 

You can put the following code to advanced editor in power query

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WSkxKNjI2SUlNU9JRKkysKi+ugIkoxepEK5mkpiSXAaWAImAWSMzQyBioEigIpmJjAQ==", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Column1 = _t, Column2 = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"Column1", type text}, {"Column2", type text}}),
    #"Added Custom" = Table.AddColumn(#"Changed Type", "Custom", each Text.Combine(List.Intersect({Text.ToList([Column1]),Text.ToList([Column2])}))),
    #"Added Custom1" = Table.AddColumn(#"Added Custom", "Custom.1", each if [Custom]<>null then "Matched" else "Not Matched")
in
    #"Added Custom1"

Output
