Hi everyone,

I am fairly new to Node-Red and am trying to change JSON Object keys.

I have two GPS Trackers that output their tracking data as per the msg.payloads below.

![13%20PM](https://us1.discourse-cdn.com/flex026/uploads/nodered/original/2X/4/411c56dbf4c3230207edad181c742d4baf521966.png)

I will need to change the JSON Object keys of latitudeDeg and longitudeDeg to latitude and longitude and have tried with a Change node, below, with no success. Am I using the proper syntax/method?

Thank you for your help!!

Just set new properties to the existing ones.

Set :: msg.payload.latitude :: to :: msg.payload.latitudeDeg

and so on.

Set will copy them  
So maybe use move instead ?
