Hey @gnik31!

You can use the [Function node](https://docs.n8n.io/nodes/n8n-nodes-base.function/#function) for that. Note that the Function node returns an array. Sharing a code snippet with you that might help

```nohighlight
var newArr = []
// code to transform/extract the data
newArr.push({json: {Key1: value1, Key2: value2}})

return newArr

```

Please let us know if you have any other questions. You can read more about the data structure in n8n [here](https://docs.n8n.io/reference/data/data-structure.html#data-structure)

Hope this helps!

Hi, sorry I’m new to n8n and TS as a language… I can not get an array of items out; similar but slightly different because I have multiple items.  
e.g.

```auto
[
  [
    {
      "Key": "ec37c11e-2b67-49c6-8a58-6eccb7dd75ee",
      "Name": "Customer"
    },
    {
        "Key": "0dbdbf8a-d80c-48e6-b453-bb7862445b7c",
        "Name": "InventoryItem"
    },
    {
        "Key": "6d2dc48d-2053-4e45-8330-285ebd431242",
        "Name": "Supplier"
    },
    {
        "Key": "dcb382dc-a4e0-4354-a845-b7d647f610f7",
        "Name": "CustomField"
    }
  ]
]

```

I’ve been trying to go over the documentation but there are a few 404’s when important. e.g. as in " Information about how the data is structured can be found on [this](https://docs.n8n.io/getting-started/key-concepts.html#data-structure) page about data structures."

</div>

Ok so this is what ended up working to structure it how I needed it…

```auto
const newItems = [];

var max = $node["HTTP Request"].json.length;
for (let i=0;i<max;i++) {
  newItems.push({json:{ key: $node["HTTP Request"].json[i]["Key"], Name: $node["HTTP Request"].json[i]["Name"]}});
}

return newItems;

```

I’m sure this could be cleaner…

We have a new node that we’re putting the finishing touches to that will do exactly this.
