Here is the code for the below Json output:

let params : [[String : AnyObject]]  = [["name" : "action", "value" : "pay" ],["name" : "cartJsonData" , "value" : ["total": 1,"rows":[["quantity": “1” ,"title":"Donation for SMSF India - General Fund","price":"1","itemId":"DN001","cost": “1”,”currency":"INR"]]]], ["name" : "center", "value" : "Chennai"], ["name" : "flatNumber", "value" : "503"], ["name" : "panNumber", "value" : ""], ["name" : "payWith"], ["name" : "reminderFrequency","value" : "Monthly"],  ["name" : "shipToAddr1"], ["name" : "shipToAddr2"], ["name" : "shipToCity"], ["name" : "shipToCountryName" , "value" : "India"], ["name" : "shipToEmail", "value" : “[email protected]"], ["name" : "shipToFirstName" , "value": "4480101010"], ["name" : "shipToLastName"], ["name" : "shipToPhone", "value" : "4480101010"], ["name" : "shipToState"], ["name" : "shipToZip"], ["name" : "userId", "value" : “null”], ["name" : "shipToCountry", "value" : "IN"]]  var jsonObject: NSData? = nil  do {    jsonObject = try NSJSONSerialization.dataWithJSONObject(params, options: NSJSONWritingOptions())    print(jsonObject) // This will print the below json.  }  catch{} 

By printing jsonObject, I got this one.

[{ "value": "pay", "name": "action" }, { "value": { "rows": [{ "price": "1", "quantity": "1", "cost": "1", "currency": "INR", "itemId": "DN001", "title": "Donation for SMSF India - General Fund" }], "total": 1 }, "name": "cartJsonData" }, { "value": "Chennai", "name": "center" }, { "value": "503", "name": "flatNumber" }, { "value": "", "name": "panNumber" }, { "name": "payWith" }, { "value": "Monthly", "name": "reminderFrequency" }, { "name": "shipToAddr1" }, { "name": "shipToAddr2" }, { "name": "shipToCity" }, { "value": "India", "name": "shipToCountryName" }, { "value": "[email protected]", "name": "shipToEmail" }, { "value": "4480101010", "name": "shipToFirstName" }, { "name": "shipToLastName" }, { "value": "4480101010", "name": "shipToPhone" }, { "name": "shipToState" }, { "name": "shipToZip" }, { "value": "null", "name": "userId" }, { "value": "IN", "name": "shipToCountry" }]

And I want the JSON to be in the below format.

[{ “name”: “action”, “value”: “pay” }, { “name”: “cartJsonData”, “value”: “{\”total\”:1,\”rows\”:[{\”itemId\”:\”DN002\”,\”title\”:\”Donation for SMSF India - General Fund\”,\”quantity\”:\”100\”,\”currency\”:\”INR\”,\”price\”:\”1\”,\”cost\”:\”100\”}]}” }, { “name”: “center”, “value”: “Chennai” }, { “name”: “flatNumber”, “value”: “ “ }, { “name”: “panNumber”, “value”: “ASSDDBBDJD” }, { “name”: “payWith” }, { “name”: “reminderFrequency”, “value”: “Monthly” }, { “name”: “shipToAddr1” }, { “name”: “shipToAddr2” }, { “name”: “shipToCity” }, { “name”: “shipToCountryName”, “value”: “India” }, { “name”: “shipToEmail”, “value”: “[email protected]” }, { “name”: “shipToFirstName”, “value”: “Raju” }, { “name”: “shipToLastName” }, { “name”: “shipToPhone”, “value”: “1234567890” }, { “name”: “shipToState” }, { “name”: “shipToZip” }, { “name”: “userId”, “value”: “null” }, { “name”: “shipToCountry”, “value”: “IN” }]

How can it be done? Only the value in cartJsonData needs to be changed. Can someone help me on this to solve it?

Try this.

func jsonToString(json: AnyObject){         do {           let data1 =  try NSJSONSerialization.dataWithJSONObject(json, options: NSJSONWritingOptions.PrettyPrinted) // first of all convert json to the data             let convertedString = String(data: data1, encoding: NSUTF8StringEncoding) // the data will be converted to the string             print(convertedString) // <-- here is ur string            } catch let myJSONError {             print(myJSONError)         }      }
