Does it support all SQL dialects?

The formatter supports standard SQL and has specific handling for MySQL, PostgreSQL, and T-SQL (SQL Server) dialects via a selector.

Does it validate SQL syntax?

The formatter is structure-based, not a full SQL parser. It formats based on keyword patterns and may not catch all syntax errors.
