SQL Formatter & Query Beautifier
Format, indent, and beautify complex SQL queries for PostgreSQL, MySQL, SQLite, and SQL Server client-side in your browser.
Why Clean SQL Formatting Improves Code Reviews & Query Performance
In backend development, ORM query log outputs (from Prisma, TypeORM, Drizzle, Hibernate, or Entity Framework) frequently generate unformatted single-line SQL strings that are difficult for engineers to read or debug during code reviews.
Best Practices for Readability
- Capitalized Keywords: Standardize SQL reserved words (
SELECT,FROM,WHERE,JOIN) in uppercase to distinguish keywords from table and column identifiers. - Clause Isolation: Break major SQL clauses onto separate lines for visual clarity when reviewing execution plans (`EXPLAIN ANALYZE`).
How to Use SQL Formatter & Query Beautifier
- Paste your unformatted or single-line SQL query into the input box.
- Click "Format SQL" or start typing to standardize uppercase keywords and clause line breaks.
- Click "Copy Result" to copy the beautified SQL query into your IDE or database management tool.
Examples
Format Raw Query Log
select u.id, u.email, o.total from users u join orders o on u.id = o.user_id where o.status = "completed" order by o.total desc
SELECT u.id, u.email, o.total
FROM users u
JOIN orders o ON u.id = o.user_id
WHERE o.status = "completed"
ORDER BY o.total DESC
Frequently Asked Questions
Which SQL dialects are supported?
The formatter standardizes common ANSI SQL keywords used across PostgreSQL, MySQL, MariaDB, SQLite, Microsoft SQL Server (T-SQL), and Oracle.
Are my database queries sent to remote servers?
No. Query beautification is executed 100% locally in your web browser. Confidential table names, column structures, and query parameters remain private.
