How do I convert a PROTOBUF file to NDJSON using LetsConvert?

Go to the PROTOBUF to NDJSON converter page, upload your PROTOBUF file, and optionally provide a .proto schema to preserve original field names and enum values. Click 'Convert' to decode each binary message into a JSON object, and download the NDJSON file where each line represents one decoded message.

Why should I convert PROTOBUF to NDJSON?

PROTOBUF is a compact binary format that requires a schema to interpret, while NDJSON is plain text and self-describing. Converting to NDJSON makes data easy to inspect with tools like jq, stream into data pipelines such as BigQuery or Kafka, and process with languages that handle JSON natively. It also simplifies debugging and ad-hoc analysis.

How does the conversion preserve Protobuf data types, nested messages, and binary fields?

Scalar types like int, float, bool, and string are mapped to their JSON equivalents. Nested messages become nested JSON objects, and repeated fields become arrays. Protobuf 'bytes' are base64-encoded to remain safely representable in text. Enums are output as their numeric values by default, or as name strings if a .proto schema is supplied. Unset optional fields are omitted, mirroring the original message semantics.

Is PROTOBUF-TO-NDJSON free to use?

Yes, PROTOBUF-TO-NDJSON on LetsConvert is 100% free with no registration or hidden fees required.

Are my uploaded files safe and secure?

Does this converter work on mobile phones and tablets?

Is there any software installation required?
