OPC-UA to Azure-IOT hub

Hi,
I am trying to send PLC tag data to azure iot hub using OPC UA

I am able to read the tags from PLC and using Join node able to convert into object of Key-value.

How we can convert the object of key-value to single object to send to iot hub to display data on powerBI.

Pls help

Thanks
