How do I convert NDJSON to AVRO using LetsConvert?

Upload your .ndjson file, select AVRO as the target, and optionally paste an Avro schema. If no schema is provided, the tool automatically infers it from the first JSON line, then maps each newline-delimited record to Avro's binary format. After processing, download your .avro file and verify it in tools like AvroTools or Spark.

Why should I convert NDJSON to AVRO instead of keeping the file as JSON?

NDJSON is human-readable and convenient for streaming but stores data as plain text. Avro is a compact binary format with an explicit schema, reducing storage by up to 80%, enabling schema evolution, and providing built-in support in Big Data systems like Apache Spark, Kafka, and Hadoop. It also allows pluggable compression codecs like Snappy and Deflate.

How does the conversion handle data types and nested structures from NDJSON to AVRO?

Each JSON object becomes an Avro record. Primitive types (string, number, boolean, null) map directly to Avro types. Nested objects become Avro records, and arrays become arrays. If a field has varying types across lines, a union type is created. Logical types such as timestamps are recognized when they match ISO 8601 patterns, preserving precision.

Is NDJSON-TO-AVRO free to use?

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