Avro encoder and decoder

Use this Avro encode and decode tool to convert Avro binary data into readable JSON, or encode JSON back into Avro binary using a schema. It is useful when debugging event streams, Kafka payloads, schema registry data, and services that exchange compact Avro messages.

The conversion runs locally in your browser, so schemas and payloads are not uploaded while you inspect or transform them.
