Format, beautify, or minify SQL queries — supports all major SQL dialects.
SQL Formatter is a free online tool that formats, beautifies, and minifies SQL queries for all major database dialects. It transforms messy, single-line SQL into a well-structured, readable format with proper indentation, keyword capitalization, and logical line breaks. The tool supports multiple SQL dialects including MySQL, PostgreSQL, SQLite, Microsoft SQL Server, Oracle, and standard SQL. It handles complex queries with subqueries, JOINs, CTEs (Common Table Expressions), window functions, and nested conditions. Keywords are automatically capitalized for better readability. Properly formatted SQL is essential for debugging complex queries, conducting code reviews, and maintaining database scripts. When working with auto-generated SQL from ORMs like Eloquent, ActiveRecord, or Hibernate, this formatter makes the output human-readable for optimization and debugging. Everything runs entirely in your browser. Your SQL queries are never sent to any server, making it safe for queries containing sensitive table names, business logic, and data patterns. There are no usage limits and no account required. Common use cases include formatting ORM-generated queries for debugging, beautifying stored procedures, preparing SQL for documentation, cleaning up migration scripts, and making complex analytical queries readable. The tool also supports minification for embedding SQL in application code.
