Table.AggregateTableColumn with list of list and conditional function

[PhilippeMuniesa]

Hello,

I have a table with several columns, I created a list of column headers. then I grouped in a DATA column the columns of the table without aggregation. I would then like to expand the tables in the DATA column using different aggregations based on the column name (element of the list of column names).

I tried .... ,

Aggreg2 = Table.AggregateTableColumn(
Groupe_table,
"Data",
List.Transform(My_Liste, each {if _ (Text.Contains(_,"50.002")) then List.Max else List.Sum, _, type number})
),

but obviously the syntax is wrong. Attached is a link to download the table and the request in excel.

Thanks for any help

I think your aggregation list is incorrect syntax.

Try:

List.Transform(My_Liste, each if Text.Contains(_,"50.002") then {_, List.Sum, "sum of " & _, type number} else {_, List.Max, "Max of " & _, type number})

Thank you very much,

I still have a bit of trouble with lists and list.transform
