Hola Francisco!!! Sí, claro que dependiendo de las necesidades de cada escenario, Excel o Power Query pueden ser la solución ideal. En lo personal Power Query ha sido la mejor 😊 Un abrazo 🤗

Que gusto me da verte de regreso, Ale!! Agradezco y valoro mucho tus aportes, he aprendido mucho con tus videos. Ultimamente me he dado cuenta que cada que trabajo con tablas, hay ciertas rutinas que termino realizando con frecuencia del tipo: Elimina columnas Vacias, transforma a null los campos vacios, transforma a mayusculas los titulos de las columnas, etc. Te pasa lo mismo?, Sería lindo un video con las normalizaciones más comunes :)

As always, great video, and learned something new! Question though, what would the impact be of using a list buffer in the nested monthly lists? Would it help or hinder?

Thank you Mathew, Great point! In this example, it doesn't seem to make a difference; however, in my experience with longer datasets, using List.Buffer can have a big impact reducing the time calculating & loading. Just keep in mind that you will be impacting the use of memory, when using List.Buffer or Table.Buffer. Here is how the code would look for this video, using List.Buffer for nested tables: let Source = Excel.CurrentWorkbook(){[Name="Demo1"]}[Content][[Date], [Daily Sale]], SOM = Table.AddColumn(Source, "Start of Month", each Date.StartOfMonth([Date]), type datetime), Grouped = Table.Group(SOM, {"Start of Month"}, {{"SOM", each let a = Table.AddIndexColumn (_, "I", 1), x = List.Buffer(a[Daily Sale]), b = Table.AddColumn(a, "YTD", each List.Sum (List.Range(x, 0, [I] )) ) in b}}), TblsCombine = Table.Combine (Grouped[SOM], {"Date", "Daily Sale", "YTD" }), CT = Table.TransformColumnTypes(TblsCombine,{{"Date", type date}, {"Daily Sale", Int64.Type}, {"YTD", Int64.Type}}) in CT
