SQL Formatter: How to Beautify SQL Queries Online

SQL formatting transforms messy, hard-to-read SQL queries into well-structured, readable code. Proper SQL formatting is essential for code reviews, debugging, and team collaboration.

What is This?

SQL formatting (or beautifying) is the process of organizing SQL code with consistent indentation, line breaks, and keyword capitalization. A SQL formatter automatically applies formatting rules to make your queries readable and maintainable.

How to Format SQL Queries

1. Paste your SQL query into our formatter
2. Select your preferred formatting style (standard, compact, or expanded)
3. Choose keyword case (UPPERCASE, lowercase, or Capitalize)
4. Click "Format SQL" to beautify your query
5. Copy the formatted SQL for use in your project

Benefits

• Improved Readability: Easily understand complex queries at a glance
• Faster Debugging: Spot syntax errors and logic issues quickly
• Better Collaboration: Team members can read and modify queries easily
• Code Reviews: Consistent formatting makes code reviews more effective
• Learning Tool: See SQL best practices demonstrated in your own code

Common Use Cases

Legacy Code Cleanup

Inherited a database with messy SQL views and stored procedures? Format all SQL code to modern standards for better maintainability. Formatted SQL helps new team members understand the codebase faster.

Code Review Preparation

Before submitting SQL code for review, format it consistently to help reviewers focus on logic rather than style issues. Many teams enforce SQL formatting standards in their style guides.

Learning SQL

Students learning SQL benefit from formatted queries that clearly show structure and syntax. Formatted examples make it easier to understand JOINs, subqueries, and complex WHERE clauses.

Database Migration

When migrating between database systems (MySQL to PostgreSQL, etc.), format queries to match the target system's conventions and identify compatibility issues more easily.

Tips & Tricks

• Consistent keyword case: Choose UPPERCASE or lowercase for SQL keywords and stick to it across your team
• Indent subqueries: Always indent nested queries to show hierarchy clearly
• One column per line: In SELECT statements, list each column on a new line for better readability
• Align JOIN clauses: Align JOIN keywords and conditions for complex multi-table queries
• Use formatting tools: Automate formatting with tools to save time and ensure consistency

Conclusion

SQL formatting is a simple practice that dramatically improves code quality and team productivity.
