SQL Formatter & Beautifier
Paste SQL to format, beautify, and make it readable. Everything runs locally in your browser.
What is SQL Formatting?
SQL (Structured Query Language) is the standard language for database queries. In production environments, SQL queries are often minified to a single line for efficiency. While this saves space, it makes debugging and code review nearly impossible.
This SQL formatter takes your compact or messy SQL and outputs clean, properly indented SQL that's easy to read. It handles complex queries with JOINs, subqueries, CTEs, and window functions. The formatter recognizes SQL syntax and intelligently adds line breaks and indentation.
Unlike other online SQL tools, qtoolkit.dev processes everything client-side in your browser. Your queries never leave your machine, making it safe for production queries with sensitive data.
Supported Features
Multiple SQL dialects (MySQL, PostgreSQL, SQL Server, Oracle, SQLite), keyword capitalization, indentation control, comment preservation, and handling of complex queries with CTEs and window functions.
