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, entirely in your browser.
- Is my Avro data uploaded anywhere?
- No. Your file is parsed entirely in your browser using WebAssembly — it is never uploaded or sent to any server.
- Can I export the parsed data?
- Yes. Use the "Export JSON" button to download the parsed records as a JSON file.
