SQL Formatter

About this tool

SQL formatting transforms dense, hard-to-read queries into well-structured, maintainable code. Proper indentation and keyword placement make complex joins, subqueries, and multi-table operations understandable at a glance. Our SQL Formatter follows industry best practices to create clean, professional SQL code.

Whether you're debugging production queries, reviewing team code, documenting database operations, or learning SQL, formatted queries are essential. A well-formatted query reveals logical errors, makes optimization opportunities obvious, and serves as self-documenting code that other developers can understand instantly.

This formatter supports all major SQL dialects including MySQL, PostgreSQL, SQL Server (T-SQL), Oracle PL/SQL, and SQLite. It handles complex queries with multiple joins, nested subqueries, CASE statements, window functions, and CTEs (Common Table Expressions). All formatting happens locally in your browser for maximum privacy.

The tool automatically capitalizes SQL keywords (SELECT, FROM, WHERE), aligns clauses for visual clarity, and properly indents nested queries and logical operations. This makes even the most complex queries readable and maintainable.

Usage examples

Before: select id,name,email from users where status='active'

  name,
  email
FROM users
WHERE status = 'active'
