Which SQL dialects are supported?

The formatter works with standard SQL and is compatible with MySQL, PostgreSQL, SQLite, SQL Server, and Oracle syntax. Dialect-specific functions are passed through without modification.

Does the formatter validate SQL syntax?

No — it formats the structure using keyword-based rules. Syntax errors in your SQL are not detected. Use your database client or a linter for validation.

Can it format complex queries with CTEs and subqueries?

Yes. CTEs (WITH clauses), subqueries, JOINs, and window functions are all formatted. Very complex nesting may need minor manual adjustment.

Why should I format SQL?

Formatted SQL is significantly easier to read, debug, and review. Consistent indentation makes JOIN conditions, WHERE clauses, and column lists immediately visible.

Is my SQL sent to a server?

No. All formatting runs as pure JavaScript in your browser. Your queries are never transmitted anywhere.
