Drop Avro file here

Server processing — includes Snappy/Zstandard-compressed files

What is an Avro file viewer?

Apache Avro is a compact, schema-based binary format commonly used in Kafka topics and big data pipelines. This tool decodes Avro files — including Snappy- and Zstandard-compressed ones — on the server and lets you preview records, inspect columns, and export the results as JSON.

Frequently Asked Questions

What is an Avro file?
Apache Avro is a row-based binary serialization format widely used in data streaming and big data pipelines, such as Kafka, Hadoop, and Spark. Each file embeds its own schema alongside the data.
Does this tool support compressed Avro files?
Yes. Avro files compressed with Snappy, Zstandard, or Deflate codecs are decoded automatically on the server.
Is my Avro data uploaded anywhere permanent?
Your file is sent to the backend only to decode the binary format and generate a preview. It is not stored permanently or shared with third parties.
Can I export the parsed data?
Yes. Use the "Export JSON" button to download the parsed records as a JSON file.
