Hi evereyone, I trying to figure out how to format may payload output like this { S1: "A", S2: "C" } to "A,C".  
I tried to code in a function

```auto
var myJSON = msg.payload;
var str = JSON.stringify(myJSON);
return str;

```

But not the output I was expecting.

Try

var str = JSON.stringify(Object.values(myJSON));

```

Hi.. this is my output of my new version using the code suggested [2,3,"A,0",1] but I noticed it is not in the right order should be ["A,0",1.2,3] what do you think causes it and my end goal is to have it this format when placed in a variable _ **str1 = "A,0,1,2,3"** _ I tried to come up with a solution but no avail.

What exactly was the value of `msg.payload` you had to get this result?

I'm getting this value in the debug {"S1":"A,0","S2":1,"S3":2,"S4":3}

If S1 and S2 are always the keys to use then add a function nodes and so this...

```auto
let data = msg.payload;
let arr = [data.S1, data.S2];
msg.payload = arr.join(",");
return msg;

```

If you are saying there are a variable amount of S1, S2, S3...Sn then

```auto
let data = msg.payload;
let i = 1;
let arr = [];
while(data["S"+i] != null) {
  arr.push(data["S"+i]);
  i++;
}
msg.payload = arr.join(",");
return msg;

```

EDIT - updated (added the important `i++` - oops)
