How do I convert a SQL file to AVRO with LetsConvert?

On the SQL-to-AVRO page, upload your .sql file or paste the SQL schema and INSERT statements. Choose an optional compression codec (deflate, snappy, or zstd), then click Convert. The tool parses CREATE TABLE and INSERT statements, maps each column to an Avro field with matching type, and returns a binary .avro file for download.

Why convert SQL to AVRO instead of keeping it in SQL or using CSV?

SQL is ideal for relational storage but heavy for large analytical pipelines. AVRO is row-oriented, compact, and schema-embedded, which makes it a natural fit for Kafka, Hadoop, and data lake ingestion. Binary encoding with optional snappy/zstd compression significantly reduces file size, and the embedded JSON schema enables schema evolution without rewriting all records.

What happens to SQL data types, NULLs, and constraints during AVRO conversion?

The converter maps SQL types to Avro logical types: INT to int, VARCHAR to string, DECIMAL to decimal (bytes), TIMESTAMP to timestamp-millis, and so on. NOT NULL columns become required Avro fields, while nullable columns are encoded as union types with null. Primary keys, indexes, and check constraints are SQL-layer features and are not carried into the Avro schema, so they are intentionally omitted.

Is SQL-TO-AVRO free to use?

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

Are my uploaded files safe and secure?

Yes! File privacy and security are guaranteed. Basic conversions run locally in your browser. Files sent for server processing are automatically deleted within 1 hour.

Does this converter work on mobile phones and tablets?

Yes! SQL-TO-AVRO works seamlessly across iPhone, Android, iPad, Mac, Windows, and Linux browsers without installing any app.

Is there any software installation required?

No software or browser extension installation is needed. All conversions are performed directly online.
