SQL Formatter & Beautifier
What is SQL formatting?
SQL formatting transforms raw, compressed, or poorly structured queries into a clean, readable format. It adds proper indentation, line breaks, and keyword alignment. As a result, complex queries become much easier to understand and debug.
Database queries in production are often written as single-line strings or generated by ORMs. Consequently, they are nearly impossible to read at a glance. A SQL formatter solves this by breaking queries into logical sections.
How to use this SQL formatter
First, paste your SQL query into the input area. Then click “Format” to beautify it with proper indentation and keyword alignment. Additionally, enable “Uppercase keywords” to automatically convert SQL keywords like SELECT, FROM, and WHERE to uppercase.
Furthermore, you can click “Minify” to compress the query to a single line. The tool also shows statistics including keyword count, table count, line count, and total file size.
Supported SQL features
The formatter supports all standard SQL statements including SELECT, INSERT, UPDATE, DELETE, and CREATE TABLE. Moreover, it handles complex features like JOINs, subqueries, CASE/WHEN expressions, GROUP BY, ORDER BY, UNION operations, window functions, and common table expressions (CTEs).
Why format SQL queries?
Readability — Formatted SQL makes it immediately clear what a query does. Therefore, team members can review and understand queries without effort.
Debugging — When a query returns unexpected results, proper formatting helps you quickly identify issues. For example, you can easily spot missing JOIN conditions or incorrect WHERE clauses.
Code reviews — Consistent SQL formatting across a team makes reviews faster. In addition, many teams enforce style guides that require specific formatting conventions.
Frequently asked questions
Does formatting change how the query executes?
No. SQL formatting only affects whitespace and letter case of keywords. The database engine produces identical results regardless of formatting.
Which SQL dialects are supported?
The formatter works with standard SQL syntax compatible with MySQL, PostgreSQL, SQLite, SQL Server, Oracle, and most other databases.
Is my data safe?
Absolutely. All formatting happens locally in your browser. Your queries never leave your device, which makes it safe for sensitive table names and data.
