```auto

            "translations":{
                "aaa":{
                    "new_id": "some text aaa"
                },
                "bbb":{
                    "new_id": "some text bbb"
                },
                "ccc":{
                    "new_id": "some text ccc"
                }
            }
        },
        {
            "id":"bbb",
            "translations":{
                "aaa":{
                    "new_id": "some text aaa"
                },
                "bbb":{
                    "new_id": "some text bbb"
                },
                "ccc":{
                    "new_id": "some text ccc"
                }
            }
        },
        {
            "id":"ccc",
            "translations":{
                "aaa":{
                    "new_id": "some text aaa"
                },
                "bbb":{
                    "new_id": "some text bbb"
                },
                "ccc":{
                    "new_id": "some text ccc"
                }
            }
        }
    ]
}

```

how to use Value setter to create “new\_id” with value somethink like translations[id].new\_id

result like

```auto
{
    "items":[
        {
            "id":"aaa",
            "new_id":"some text aaa",
            "translations":{
                "aaa":{
                    "new_id": "some text aaa"
                },
                "bbb":{
                    "new_id": "some text bbb"
                },
                "ccc":{
                    "new_id": "some text ccc"
                }
            }
        },
    ....
    ]
}

```

Hi @vosy ,

Indeed that would be easier to do with something like `translations[id].new_id` or `translations[&{id}].new_id`  
But unfortunately, it is not possible to use a variable expander inside another variable expander.  
As for your case, you can achieve by doing these **“Node transform nodes”** transformer.

1. Create a Node transformer  

2. Create a value Setter (to create a same structure so it can be compared with the “translations” data)  

3. Value setter to compare the keys  

4. Put the intersected value as a result  

As the result you’ll get this :

Let me know if this is not the result that you’re expecting.
