So I've been beating my head against the wall and need some help. I have this object:

```auto
{
    "cameras": {
        "cam1": {
            "label": "Front Door",
            "rotation": "0deg"
        },
        "cam2": {
            "label": "Driveway",
            "rotation": "0deg"
        },
        "cam3": {
            "label": "Garden",
            "rotation": "0deg"
        },
        "cam4": {
            "label": "Shed",
            "rotation": "0deg"
        },
        "cam5": {
            "label": "Backyard",
            "rotation": "0deg"
        }
    }
}

```

that I want to convert to this object:

```auto
{
    "cameras": [
        {
            "name": "cam1",
            "label": "Front Door",
            "rotation": "0deg"
        },
        {
            "name": "cam2",
            "label": "Driveway",
            "rotation": "0deg"
        },
        {
            "name": "cam3",
            "label": "Garden",
            "rotation": "0deg"
        },
        {
            "name": "cam4",
            "label": "Shed",
            "rotation": "0deg"
        },
        {
            "name": "cam5",
            "label": "Backyard",
            "rotation": "0deg"
        }
    ]
}

```

and I can't figure it out. Here is a flow with an `inject` node with the objects in it, an empty `function` node and a `debug` node anyone can play with.

```auto
[{"id":"23605468e7d390f7","type":"inject","z":"96bf579fe7b64086","name":"","props":[{"p":"payload"},{"p":"want","v":"{\"cameras\":[{\"name\":\"cam1\",\"label\":\"Front Door\",\"rotation\":\"0deg\"},{\"name\":\"cam2\",\"label\":\"Driveway\",\"rotation\":\"0deg\"},{\"name\":\"cam3\",\"label\":\"Garden\",\"rotation\":\"0deg\"},{\"name\":\"cam4\",\"label\":\"Shed\",\"rotation\":\"0deg\"},{\"name\":\"cam5\",\"label\":\"Backyard\",\"rotation\":\"0deg\"}]}","vt":"json"}],"repeat":"","crontab":"","once":false,"onceDelay":0.1,"topic":"","payload":"{\"cameras\":{\"cam1\":{\"label\":\"Front Door\",\"rotation\":\"0deg\"},\"cam2\":{\"label\":\"Driveway\",\"rotation\":\"0deg\"},\"cam3\":{\"label\":\"Garden\",\"rotation\":\"0deg\"},\"cam4\":{\"label\":\"Shed\",\"rotation\":\"0deg\"},\"cam5\":{\"label\":\"Backyard\",\"rotation\":\"0deg\"}}}","payloadType":"json","x":270,"y":200,"wires":[["507955f615e523b1"]]},{"id":"e1ea330e059e2fbe","type":"debug","z":"96bf579fe7b64086","name":"debug 33","active":true,"tosidebar":true,"console":false,"tostatus":false,"complete":"true","targetType":"full","statusVal":"","statusType":"auto","x":740,"y":200,"wires":[]},{"id":"507955f615e523b1","type":"function","z":"96bf579fe7b64086","name":"function 2","func":"\n// ???????\n\nreturn msg;","outputs":1,"noerr":0,"initialize":"","finalize":"","libs":[],"x":480,"y":200,"wires":[["e1ea330e059e2fbe"]]}]

```

Thanks in advance for anyone how can offer a solution!

Using JSONata  
set `msg.` `payload.cameras`  
to

```auto
$keys($$.payload.cameras).$merge(
   [
       {"name": $},
       $lookup($$.payload.cameras, $)
   ]
)

```

See I knew I should have asked earlier!

Thanks @E1cid, you are my hero of the day!

Javascript

```auto
let output = {cameras: []};
let cam_keys = Object.keys(msg.payload.cameras);
cam_keys.forEach(str => {
    output.cameras.push(Object.assign({name: str}, msg.payload.cameras[str]))

msg.payload = output;
return msg;

```

Or in javascript (which will be more run-time efficient, at least at the moment)

```auto
let camerasArray = []
const cameras = msg.payload.cameras
Object.keys(cameras).forEach(camera => {
    camerasArray.push({name: camera, label: cameras[camera].label, rotation: cameras[camera].rotation})
})
msg.payload = {cameras: camerasArray}
return msg;

And one more 🙂

[edit]  
It is always a pleasure to help, specially when the OP provides data examples already loaded in an inject node, and provides output examples.

Indeed. I've been mulling over an idea for some time - for the debug panel: "copy as inject" where you can then paste into the editor or forum 🙂

And if you could just automatically add the triple backticks…
