🗄️ SQL Formatter
Format and beautify SQL queries with multiple formatting styles
Understanding SQL Formatting
Why Format SQL?
Well-formatted SQL is easier to read, debug, and maintain. Consistent formatting helps teams collaborate and quickly understand complex queries.
Formatting Styles
Standard formatting uses moderate indentation and line breaks. Compact style minimizes whitespace, while expanded style adds more line breaks for maximum readability.
Best Practices
Use consistent keyword casing (typically UPPERCASE), indent nested queries, align columns in SELECT statements, and add line breaks before major clauses (WHERE, JOIN, ORDER BY).

Frequently Asked Questions
Which SQL dialects are supported?
This formatter supports standard SQL syntax and works with most SQL dialects including MySQL, PostgreSQL, SQL Server, Oracle, and SQLite.
Will this tool validate my SQL syntax?
The primary purpose is formatting, not validation. While it handles standard SQL well, it may not catch all syntax errors. Always test queries in your database.
Is my SQL query stored or sent to a server?
No, all formatting happens locally in your browser. Your SQL queries are never sent to any server and remain completely private.
What's the difference between the formatting styles?
Standard is balanced for readability, compact minimizes vertical space, and expanded adds extra line breaks for maximum clarity in complex queries.
Is this tool free to use?
Yes! This tool is completely free with no hidden costs, subscriptions, or limitations. Use it as often as you need.
