Parse CSV log from pfSense into table chart

Hi, I have set syslog-ng to forward logs to Grafana through Loki. I see the logs coming to Grafana, but they are in CSV format. I would like to parse the logs into their proper columns and display them in a table in Grafana. I tried many different methods but was not able to. Can you please give me a suggestion on how to achieve this?

Example:
4,1000000103,igb1,match,block,in,4,0x0,63,871,0,DF,6,tcp,52,10.0.1.155,45.54.49.1,41142,443,0,FA,1388582054,3600084007,347,nop;nop;TS

Thanks,
Fabio
