I want to convert the above data in to the below format :

{      
        "value" : [  
                        {  
                          "id" : "123",  
                           "name" : "testname"                                                          
                        },  
                        {  
                          "id" : "8459",  
                           "name" : "testname2"                                                
                        }  
                      ]  
}  

Could you please let me know how we can achieve this in data flow.

    Hi @Shekhar Nadide ,

    Thankyou for using Microsoft Q&A platform and posting your query .

    As I understand your requirement here, you want to convert the data present in tabular format to the objects of an array. Please correct me if my understanding is wrong.

    There is no dedicated transformation to achieve the above requirement. However, you can opt for the following approach:

    Use aggregate transformation in data flow. Leave the group by tab as blank and in aggregate tab, provide value as the columnName and use this expression collect(@(id=id,name=name,displayName=displayName)) to get the desired output in the form of array.
