About SQL Formatter & Beautifier
Writing and debugging database queries can quickly become unmanageable if the code is written in a single, unformatted block. Our free online SQL formatter helps database administrators, data analysts, and backend developers instantly beautify messy SQL scripts. By automatically parsing your raw query, it applies standardized indentation, capitalizes specific system keywords, and intelligently places line breaks before major clauses like SELECT, JOIN, and WHERE to drastically improve structural readability.
This versatile SQL syntax beautifier is compatible with all major database dialects including MySQL, PostgreSQL, SQL Server, and SQLite. In addition to expanding condensed code, you can also use this tool to minify formatted queries by stripping out unnecessary whitespace—perfect for preparing queries for application deployment. Everything from keyword casing preferences to tab indentation size is completely customizable, and because processing happens natively in your browser, your proprietary database schemas are never exposed to remote servers.
