Convert namedtuple to json for mqtt - thingsboard

[dbrosy]

I am attempting to upload data in json format to thingsboard from a ruuvitag. I have the data from the device as a namedtuple but need to convert it.
What is the best way to convert this?

data

RuuviTagRAW(mac='aa:aa:aa:aa:aa:aa', rssi=-49, format=5, humidity=47.7525, temperature=22.25, pressure=102188, acceleration_x=8, acceleration_y=-16, acceleration_z=1008, battery_voltage=2953, power_info=4, movement_counter=24, measurement_sequence=6190)

required json

{
    "RuuviTagRAW": [
        {
            "mac": "aa:aa:aa:aa:aa:aa",
            "rssi": "-49",
            "format": "5",
