Sort files by month

[dadb25]

Hi Community,

I use data in a Sharepoint folder, where 3 news files are automatically stored every days.

I want to sort them, to keep the 3 earliest files (sorted by column modified).

For the current month, I know how to do it, but how can I sort these files for every months ?

Meaning, I need the 3 last files for January, for December and so on ... ?

Thank you

Regards

Hi @dadb25 

So you want the 3 most recent files for every month ?

Essaye cela dans ton code, 

let
    Source = Ta Source SharePoint,
    AddYear = Table.AddColumn(Source, "Year", each Date.Year([Date modified]), type number),
    AddYearMonth = Table.AddColumn(AddYear, "Month", each Date.Month([Date modified]), type number),
    SortedFiles = Table.Sort(AddYearMonth, {{"Date modified", Order.Descending}}),
    GroupedFiles = Table.Group(SortedFiles, {"Year", "Month"}, {
        {"AllData", each _, type table}}),
    AddIndexAndFilter = Table.TransformColumns(GroupedFiles, {
        "AllData", each Table.FirstN(Table.AddIndexColumn(_, "Index", 1, 1, Int64.Type), 3)
    })
in 

AddIndexAndFilter

Ensuite tu developpes la colonne Data et tu gardes les colonnes que tu veux
