SQL Formatter

SQL formatting (or beautifying) adds proper indentation, line breaks, and capitalization to SQL queries to make them more readable. It helps developers understand complex queries, debug issues, and maintain consistent code style across teams.

This formatter supports Standard SQL, MySQL, PostgreSQL, and SQLite. While the core SQL syntax is similar across databases, each has specific keywords and functions. Select your database dialect for best results.

This is primarily a formatter, not a validator. It will format valid SQL and attempt to format invalid SQL, but it won't catch all syntax errors. For validation, test your queries in your actual database environment.

The AI Optimize feature analyzes your SQL query and provides suggestions for improving performance, readability, and best practices. It can identify missing indexes, inefficient joins, and opportunities for query optimization.

Yes, this formatter handles SELECT, INSERT, UPDATE, DELETE, CREATE, ALTER, and other SQL statements. It works with subqueries, joins, CTEs, and most SQL constructs. Very complex stored procedures may require manual adjustment.

Absolutely. This tool runs entirely in your browser using JavaScript. Your SQL queries never leave your computer or get sent to any server. All formatting happens locally on your device.
