How to retrieve data from recursive JOSN

Hi All,

 

I have  a JOSN file and the data in it is like below.

 

{

                "firstName": "Bidhan",

                "lastName": "Chatterjee",

                "age": 40,

                "address": {

                                "streetAddress": "144 J B Hazra Road",

                                "city": "Burdwan",

                                "state": "Paschimbanga",

                                "postalCode": "713102"

                },

                "phoneNumber": [{

                                                "type": "personal",

                                                "number": "09832209761"

                                },

                                {

                                                "type": "fax",

                                                "number": "91-342-2567692"

hi  @AnandNamburi 

you could try this way to retrieve data

let
    Source = Json.Document(File.Contents("C:\Users\Desktop\new.json")),
    #"Converted to Table" = Record.ToTable(Source),
    #"Pivoted Column" = Table.Pivot(#"Converted to Table", List.Distinct(#"Converted to Table"[Name]), "Name", "Value"),
    #"Expanded address" = Table.ExpandRecordColumn(#"Pivoted Column", "address", {"streetAddress", "city", "state", "postalCode"}, {"streetAddress", "city", "state", "postalCode"}),
    #"Expanded phoneNumber" = Table.ExpandListColumn(#"Expanded address", "phoneNumber"),
    #"Expanded phoneNumber1" = Table.ExpandRecordColumn(#"Expanded phoneNumber", "phoneNumber", {"type", "number"}, {"type", "number"})
in
    #"Expanded phoneNumber1"

Result:

This is not recursive, it's just a multi level hierarchy - that's what JSON is about.  

 

In Power Query you need to manually traverse that hierarchy and pick the fields that you want to convert into a flattened version. There's no magic "give me all the JSON data in a flat table" button, it's all manual work.
