C# convert AVRO to JSON

Question

Is there C# implementation to convert an AVRO deserialized

<GenericRecord>

back into a regular JSON format? I have successfully read the topic from Kafka and used the AvroDeserializer but I want to convert that into a JSON format.

Here's an example: Simple JSON:

{       
        "value": {
            "eventCreatedTimestamp": 1588694347577,
            "iouDecision": "PLANE",
            "iouDecisionReason": {
                "value": "Optimal"
            }
        }
    }

Same from the AVRO deserialized Generic.Record:

{Schema: 
{"type":"record","name":"TheCustomerDecisionEvent",
"namespace":"com.farmxxx.tst.property.service.options.iou.messaging.avro","fields":
[{"name":"eventCreatedTimestamp","type":["null","long"]},
{"name":"iouDecision","type":["null",{"type":"enum",
"name":"TheType",
"namespace":"com.farmxxx.tst.property.service.options.iou.messaging.avro",
"symbols":["HRMR","FIELD","PLANE"]}]},
{"name":"iouDecisionReason","type":["null",{"type":"record","name":"iouDecisionReason",
"namespace":"com.farmxxx.tst.property.service.options.iou.messaging.avro",
"fields":[{"name":"value","type":["null","string"]}]}]}]}
,
 contents: { eventCreatedTimestamp: 1588694347577, 
 iouDecision: Schema: {"type":"enum","name":"TheType",
 "namespace":"com.farmxxx.tst.property.service.options.iou.messaging.avro",
 "symbols":["HRMR","FIELD","PLANE"]}, value: PLANE,
 iouDecisionReason: Schema: {"type":"record","name":"iouDecisionReason",
"namespace":"com.farmxxx.tst.property.service.options.iou.messaging.avro",
"fields":[{"name":"value","type":["null","string"]}]}, contents: { value: Optimal, }, }}

So the task is to get back to the Simple JSON from the AVRO Generic.Record.

The solution can be found using:

https://github.com/AdrianStrugala/AvroConvert

Avro2Json feature.

With this you can read a topic from Kafka and translate that into simple JSON. I use that simple JSON to pass onto other clients who don't want to know about AVRO record format etc.

Many thanks to the author of the AvroConvert Github repository.
