Free Online SQL Formatter & Beautifier

What is an SQL Formatter?

An SQL Formatter (or SQL Beautifier) is a tool that automatically reformats SQL (Structured Query Language) code to make it more readable and maintainable. It applies consistent indentation, spacing, line breaks, and often case conventions for keywords, improving the overall structure and appearance of complex queries. This helps developers understand, debug, and share SQL code more effectively.
