Hi all,

I'm looking for a way to parse the JSON that I'm receiving from a MQTT communication.  
I'm receiving the following structure:

_IOLM/port/1/pdi : msg.payload : string[163]_  
_"{"port":1,"valid":1,"uint":8716289,"PD\_ProcessData\_IN":{ "Flow":133,"Error":false,"Fixed\_output":false,"HHH\_LLL":false,"OUT2":false,"OUT1":true},"raw":[0,133,0,1]}"_

However, I would like to look only into the Flow information, such as:  
Flow:133

Thank you guys  
Regards  
Marcos

Hi @smarcos212

Configure the MQTT node to output a parsed JSON object. That will do all the work for you.

You will then be able to access `msg.payload.PD_ProcessData_IN.Flow` to access the value you mention.
