SQL Formatter & Minifier

Format, minify, and syntax-highlight SQL queries with proper indentation and keyword uppercasing.

What is a SQL Formatter?

A SQL formatter (or SQL beautifier) takes raw SQL queries and reformats them with consistent indentation, capitalization, and line breaks. Well-formatted SQL is easier to read, debug, and maintain — especially for complex queries with multiple joins, subqueries, or CTEs (Common Table Expressions). Consistent formatting also helps teams follow coding standards during code reviews.

This tool formats SQL queries for multiple dialects including MySQL, PostgreSQL, SQLite, and standard SQL, all processed directly in your browser.

How to Use This SQL Formatter

Paste your SQL — Copy your SQL query and paste it into the input editor.
