@fahadmicro You can use the [Node, transform nodes](https://forum.alumio.com/t/node-transformer/348) entity transformer to loop through the `line_items` in your Shopify order entity. Inside the node transformer, you can then transform each line item to match the `Groups.0.Transactions.0.PO1Loop` format.

However, in order to get the index of each line item, before entering the above Node transformer, you should put use the [Move data between accessors](https://forum.alumio.com/t/move-data-between-accessors/284) to map the index of `line_items` array into an accessible property inside the each `line_items` object. See the below picture.

The above transformer will result in the below `PO1loop` array.

```auto
{
  "PO1loop": [
    {
      "index": "0", // the index
      "line_item": {
        ...
        "id": 669751112,
        "price": "199.99",
        "product_id": 7513594,
        "quantity": 1,
        "requires_shipping": true,
        "sku": "IPOD-342-N",
        "title": "IPod Nano",
        "variant_id": 4264112,
        "variant_title": "Pink",
        ...
      }
    },
    {
      "index": "1", // the index
      "line_item": {
        ...
        "id": 669751113,
        "price": "199.99",
        "product_id": 7513594,
        "quantity": 1,
        "requires_shipping": true,
        "sku": "IPOD-342-N",
        "title": "IPod Nano",
        "variant_id": 4264112,
        "variant_title": "Pink",
        ...
      }
    }
  ]
}

```

You can use the Node transformer to loop through the `PO1loop` array instead of looping through the original `line_items` array.
