Hi @Mederic,

Result

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WMlTSUUrUSdJJVorViVYyAvJSdFLBbGMgO00nXSdDJ1MpNhYA", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Col1 = _t, Col2 = _t]),
    ChangedType = Table.TransformColumnTypes(Source,{{"Col1", Int64.Type}}),
    Ad_Col3 = Table.AddColumn(ChangedType, "Col3", each 
        [ a = Text.Split([Col2], ","),
          b = List.Transform(a, (x)=> Text.From([Col1]) & Text.Trim(x)),
          c = Text.Combine(b, ", ")
        ][c], type text)
in
    Ad_Col3
