You need a data structure to work with, eg:

static struct S {
   string characteristicValue;
}

foreach (ref j; parseJson(data)["items"].byElement()) {
   auto sArr = j["type"].deserialize!(S[]);
   writefln("value: %s", s[0].characteristicValue);
}

Then split your S.characteristicValue into tokens with 
std.array.split


writefln("value: %s", sArr[0].characteristicValue);


Hi,

 Thank you very much, your solution resolved the issue.

Hi All,

   Request your help on how to get the first value of "type" from 
the below json, the expected output required is as below,


{"characteristicValue":"TT,t...@dev.com,DEV"}

output1: TT
output2: t...@dev.com

Code:

/+dub.sdl:
dependency "asdf" version="~>0.6.6"
+/
import std;
import asdf;

void main()
{
 string data = `{"items":[{
  "hostname":"test01",
  "type":[
  {"characteristicValue":"TT,t...@dev.com,DEV"},
  {"characteristicValue":"000"}
]}]}`;

 foreach (ref j; parseJson(data)["items"].byElement()) {
writeln(j["type"]) ;
 }
}
