The input table :

Produit	Marque	Client	Année
A	Toyota	1	2018
B	Toyota	2	2019
C	Renault	3	2017
D	Toyota	4	2017

The json file to generate:

{

‘Datas’ : [

{Marque : ‘Toyota’, Produits : [A, B, D], Clients : [1,2,4], Année : [2017,2018,2019]},

{Marque : ‘Renault, Produits : [C], Clients : [3], Année : [2017]}

]

}

The components of the job:

I have used a tSortRow in order to sort the data on the field Marque and then used the tWriteJsonField in order to generate the json file, the problem is that i can't use multiple loop elements in order to group the data into different arrays.
