Standardized Layout
Our engine automatically handles indentation, keyword capitalization, and logical spacing to reveal the structure of nested joins and subqueries instantly.
By standardizing SQL casing (keywords in uppercase, identifiers in lowercase), you can significantly reduce syntax errors and improve code review speed.
Multi-Dialect Support
Full support for specialized syntax like PostgreSQL JSONB operators, MySQL LIMIT/OFFSET, and T-SQL TOP clauses.
Whether you're using Oracle (PL/SQL) or lightweight SQLite, we ensure the formatting rules align with your database engine's standards.
Common Questions
Is my query data safe?
Yes. All formatting happens locally in your browser. We never see your queries, tables, or database structure.
Can I use this for complex joins?
Absolutely. Our engine handles deeply nested subqueries, CTEs (WITH clauses), and complex multi-table joins.
Does it support DDL statements?
Yes! You can format CREATE TABLE, ALTER, and INDEX statements just as easily as SELECT or UPDATE queries.
Why uppercase keywords?
UPPERCASE reserved keywords (SELECT, FROM) stand out visually from table and column names, improving scanability.
