    Use this. Replace Source line completely with your source.

    let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WMlTSUTJWitWJVjICskzALGMgC8wwgTFMwYxYAA==", 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", Int64.Type}, {"Column2", Int64.Type}}),
    BuffList1 = List.Buffer(#"Changed Type"[Column1]),
    BuffList2 = List.Buffer(#"Changed Type"[Column2]),
    DiffList = List.Difference(BuffList1,BuffList2),
    Result = Table.FromColumns(Table.ToColumns(#"Changed Type")&{DiffList},Table.ColumnNames(#"Changed Type")&{"Result"})
in
    Result
