SQL formatter/beautifier

SQL Beautifier — Format and Prettify SQL Queries Online

Format and beautify SQL queries instantly online for improved readability. This SQL formatter converts minified, single-line, or poorly indented SQL into properly structured, indented, and keyword-capitalized queries. Supports standard SQL plus MySQL, PostgreSQL, Microsoft SQL Server, Oracle, and SQLite dialects.

SQL Formatting Applications

• Making database query logs readable for debugging
• Code review formatting of long SELECT/JOIN queries
• Converting ORM-generated SQL to human-readable format
• Documentation preparation of stored procedures and views
• Cleaning up manually written ad-hoc queries before sharing
• Legacy code refactoring and SQL audit

Well-formatted SQL is easier to read, debug, and review in code. This beautifier adds proper indentation to nested subqueries, capitalizes SQL keywords, aligns column lists, and structures JOIN and WHERE clauses for optimal readability. Paste any SQL query — from a simple SELECT to a complex multi-table JOIN with CTEs — and get a cleanly formatted version ready for documentation, code review, or execution.
