Extracting data from lists and combining data

Hi everyone.
 
So I have a JSON file ( need to be ) with the specific format :
 
{
    "Id":[0,1,2],
    "Data1":[[5,1],[4,81,52,6,42,8,1,4,2,5],[18,36]],
    "Date2":[["u","j","a","e"],["q","s","d","f","p"],["n","b"]],
    "Date3":[[10,13],[10,25],[10,58]]
}
 
When I load my json file as a data source, I have :
base.PNG
 

The best result I can have ( by developping ID ) is this :

have.PNG
 
But I need to have data being like this :
Capture.PNG

 

So my question is : Can I have the result I want and if yes, how ?

Here is another possible solution:

 

let
    Source = Json.Document(File.Contents("C:\Users\aolson\Downloads\Sample.json")),
    #"Converted to Table" = Table.FromColumns(Record.FieldValues(Source), Record.FieldNames(Source)),
    #"Expand Lists" = Table.TransformColumns(#"Converted to Table", List.Transform(List.Skip(Table.ColumnNames(#"Converted to Table")), (col) => {col, each Text.Combine(List.Transform(_, Text.From), ","), type text}))
in
    #"Expand Lists"
