Input SQL
Formatted
SELECT u.id, u.email, count(o.id) AS orders FROM users u LEFT JOIN orders o ON o.user_id = u.id WHERE u.created_at >= '2026-01-01' AND u.status = 'active' GROUP BY u.id, u.email HAVING count(o.id) > 5 ORDER BY orders DESC LIMIT 100;

Frequently asked questions
- Is my SQL sent to a server?
- No. The formatter runs entirely in your browser — safe to paste production queries, PII column names, and internal schema details.
- Which SQL dialects are supported?
- The formatter is dialect-agnostic and works well for PostgreSQL, MySQL, SQLite, SQL Server, Snowflake, BigQuery, and Redshift for common SELECT / INSERT / UPDATE / DELETE / CTE / window function patterns.
- What formatting rules does it follow?
- Keywords are uppercased, major clauses (SELECT, FROM, WHERE, JOIN, GROUP BY, ORDER BY, LIMIT) start on new lines, sub-clauses are indented, and multi-column lists wrap consistently. Comments and string literals are preserved.
- Why format SQL?
- Consistent formatting makes diffs readable in code review, surfaces bugs (missing JOIN condition, ambiguous alias), and speeds up scanning long queries. It's the SQL equivalent of Prettier for JavaScript.
