Answer 1

Required Data , You can get this way . Just convert that stud dict in JSon or any other format you want. Remove that array , You don't need it , As you mentioned it in the required format.

NSMutableDictionary *gradedetails = [[NSMutableDictionary alloc] init];
[gradedetails setObject:@"pass" forKey:@"studentresult"];
[gradedetails setObject:@"provided" forKey:@"marksheet"];

NSMutableDictionary *sdetails = [[NSMutableDictionary alloc] init];
[sdetails setObject:@"01" forKey:@"ID"];
[sdetails setObject:@"Name" forKey:@"Student1"];
[sdetails setObject:gradedetails forKey:@"Grade1"];

NSMutableDictionary *results = [[NSMutableDictionary alloc] init];
[results setObject:sdetails forKey:@"results"];

NSMutableDictionary *stud = [[NSMutableDictionary alloc] init];
[stud setObject:results forKey:@"Students"];

NSLog(@"Required Format Data is %@",stud);
