How do I convert an HTML file to AVRO using this tool?

Upload your HTML file or paste the markup into the input box. Next, define the Avro schema (or let the tool auto-generate one from table headers and data patterns). Click 'Convert' to parse the HTML, map the records, compress the output with Snappy, and download the .avro file.

Why should I convert HTML to AVRO instead of relying on the original HTML?

HTML is a presentation format for browsers, not a data interchange format. AVRO is a compact binary serialization format with a defined schema, making it much more efficient for storing, querying, and transferring tabular data extracted from web pages. It is natively supported in big data engines like Apache Spark, Kafka, and Hadoop, reducing storage costs and improving processing speed.

How does the conversion handle nested HTML elements and attributes?

The tool parses the HTML DOM and maps nested elements to Avro records according to your schema. HTML attributes (class, id, href, data-*) can be defined as Avro fields, and text content is extracted as UTF-8 to preserve international characters. Unused CSS or JavaScript is ignored, as they are presentational and not part of the data. If the HTML contains tables, rows are mapped to records and columns to fields.
