What is SQL Formatting?
SQL formatting transforms messy, unreadable SQL queries into clean, well-structured code. Proper formatting makes SQL easier to read, debug, and maintain.

All processing happens in your browser. Your SQL queries never leave your device and are not sent to any server.

Frequently Asked Questions
Which SQL dialects are supported?
This formatter supports standard SQL and works with MySQL, PostgreSQL, SQL Server, SQLite, and Oracle. Dialect-specific syntax is generally preserved.
Does formatting change my query logic?
No, formatting only changes whitespace and keyword casing. The logic and functionality of your query remains exactly the same.
Can I minify SQL for production?
Yes! Use the Minify button to remove all unnecessary whitespace and comments. This creates compact SQL that's ideal for embedding in code or reducing payload size.
Is my data secure?
Yes. All formatting happens entirely in your browser using JavaScript. Your SQL queries never leave your device and are not sent to any server.
