A SQL beautifier formats raw or compressed SQL queries into a clean, readable structure by uppercasing keywords and applying consistent indentation to each clause.
This tool is designed for developers, database administrators, and data analysts who frequently work with complex SQL queries. Whether you're debugging a long query pulled from application logs or preparing SQL for a code review, proper formatting makes it significantly easier to understand the query's intent and spot potential issues.
The beautifier works by normalizing all whitespace, then identifying and uppercasing standard SQL keywords such as SELECT, FROM, WHERE, JOIN, GROUP BY, ORDER BY, and many others. Major clauses are placed on their own lines, while continuation keywords like AND, OR, and ON are indented for visual hierarchy. You can adjust the indent size to match your team's coding style.
This tool supports a wide range of SQL dialects including standard ANSI SQL, MySQL, PostgreSQL, and SQLite syntax. It handles SELECT queries, INSERT/UPDATE/DELETE statements, JOINs, subqueries, and aggregate functions. The formatting is purely cosmetic and does not alter your query's logic or execution.
Paste your SQL into the input area, choose your preferred indent size, and click the button. The formatted result appears instantly with a copy button for easy use. Everything runs in your browser — no data is sent to any server.
