SQL Formatter

Free SQL Formatter and Beautifier Online

A SQL formatter takes raw, minified, or poorly structured SQL and restructures it with proper indentation and keyword casing, making complex queries readable and maintainable. Unformatted SQL from ORMs, query builders, or database exports is notoriously hard to debug: a formatter is the fastest way to understand what a query is actually doing.

How to format SQL online

1. Paste your raw SQL query into the input area.
2. Select formatting options: indent style, keyword casing (UPPERCASE recommended).
3. Click Format to beautify or Minify to compress for production.
4. Copy the formatted output or download it as a .sql file.

SQL formatting best practices

• Uppercase keywords: Write SELECT, FROM, WHERE, JOIN, and GROUP BY in uppercase to visually distinguish them from table names and column identifiers.
• One clause per line: Each major clause (SELECT, FROM, WHERE, ORDER BY) should start on a new line for readability.
• Indent subqueries: Nested SELECT statements should be indented relative to the outer query.
• Align columns in SELECT: Aligning column names in multi-column SELECT lists improves scannability during code review.

Common SQL formatting use cases

• ORM-generated queries: Format the raw SQL output from Eloquent, Hibernate, SQLAlchemy, or Prisma to understand the actual query structure.
• Database exports: Beautify SQL dump files before reviewing schema or data migrations.
• Code review: Format queries to standard style before committing stored procedures or views.
• Documentation: Clean up SQL examples for technical documentation or tutorials.
