How to Aggregate data

[Klaimand]

Hello,

Im trying to aggregate data as follow:

Current data format:

ID   Name
1       A
1       B
1       C
2       D
2       E
3       F

Expected result:

ID     Name
1        A;B;C
2         D;E
3           F

Do you know how to build this step in my query?

Best regards,

Hi @Klaimand,

Based on my test, you could refer to below formula:

Create a new table:

New Table = SUMMARIZE('Table1','Table1'[ID],"Name",CONCATENATEX('Table1','Table1'[Name],","))

Result:

You could also download the pbix file to have a view.

Hi,

This M code works

let
    Source = Excel.CurrentWorkbook(){[Name="Data"]}[Content],
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"ID", Int64.Type}, {"Name", type text}}),
    Combine = Table.Group(#"Changed Type", {"ID"}, {{"All Names", each Text.Combine(List.Distinct([Name]), "; "), type text}})
in
    Combine

Create a Measure and add the following formula:

Measure = CONCATENATEX ( VALUES ( 'Table'[Text] ), 'Table'[Text], ", " )
