    here are my operations,

    Then open the Advanced Editor, and paste the M code bellow into it

    let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WcjRUitWhnDKimIoFAA==", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Name = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"Name", type text}}),
    #"Removed Duplicates" = Table.Distinct(#"Changed Type"),
    diffday=Int16.From( Date.From(DateTime.LocalNow()) - Date.From(#date(2021,1,1)))+1,
    #"Added Custom" = Table.AddColumn(#"Removed Duplicates", "Custom", each List.Dates(#date(2021, 1, 1), diffday, #duration(1, 0, 0, 0))),
#"Expanded Custom" = Table.ExpandListColumn(#"Added Custom", "Custom")
in
    #"Expanded Custom"

    result:

    See sample file attached bellow.
