SQL Beautifier

Format and beautify your SQL queries with proper indentation and line breaks for better readability.

Syntax Highlighting

Color-coded SQL keywords, functions, strings and numbers for easier query analysis.

Multi-Dialect Support

Works with MySQL, PostgreSQL, SQL Server, Oracle and other SQL dialects.

SQL Formatting Best Practices

1. Consistent Indentation

Use consistent indentation (typically 2 or 4 spaces) for nested clauses. This makes complex queries much easier to read and understand.

SELECT u.username, u.email, o.order_date
FROM users u
JOIN orders o ON u.id = o.user_id
WHERE u.active = 1
  AND o.status = 'completed'
ORDER BY o.order_date DESC;

2. Capitalize SQL Keywords

Capitalizing keywords like SELECT, FROM, WHERE, JOIN, etc. makes them stand out from table and column names.

3. Line Breaks for Major Clauses

Put each major clause (SELECT, FROM, WHERE, GROUP BY, etc.) on a new line to visually separate query components.

4. Align Related Elements

Align similar elements vertically (like columns in SELECT, conditions in WHERE) to create visual patterns.

SELECT user_id    AS id,
       username   AS name,
       email      AS contact_email,
       created_at AS signup_date
FROM users
WHERE active     = 1
  AND verified   = 1
  AND last_login > CURRENT_DATE - INTERVAL '30 days';

5. Use Table Aliases

Use short but meaningful table aliases to make queries more concise while maintaining readability.
