Create new monthly table from one value

SeckinYilmaz - Easiest way I could think was using Power Query

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WclTSUTLUN9Q3MjAyBDGVYnWilZxQBY3AgkgqjYBME6XYWAA=", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Name = _t, Date = _t, Value = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"Name", type text}, {"Date", type date}, {"Value", Int64.Type}}),
    #"Added Custom" = Table.AddColumn(#"Changed Type", "Generated Months", each List.Transform({1 ..12}, each Number.From(_))),
    #"Expanded Custom" = Table.ExpandListColumn(#"Added Custom", "Generated Months"),
    #"Added Custom1" = Table.AddColumn(#"Expanded Custom", "Created Month", each #date(Date.Year([Date]),[Generated Months],Date.Day([Date]))),
    #"Changed Type1" = Table.TransformColumnTypes(#"Added Custom1",{{"Created Month", type date}}),
    #"Removed Columns" = Table.RemoveColumns(#"Changed Type1",{"Date", "Generated Months"})
in
    #"Removed Columns"
