Frequently Asked Questions

Find Quick Answers

What is Avro format?

Apache Avro is a data serialization system that uses JSON-based schemas and compact binary encoding. It's commonly used in big data and streaming applications.

What types of Avro data can this tool decode?

This tool can decode standard Avro binary data with embedded schemas. It supports primitive types, records, arrays, maps, unions, and enums.

Does this tool support Avro files without schemas?

No, the tool requires the Avro data to include its schema (which is standard in Avro binary encoding). For standalone schema files, you would need a different tool.

Is my data secure when using this tool?

For client-side decoding, your data never leaves your browser. For server-side processing, data is processed securely and not stored permanently.
