Open SQL FormatterBefore & After
❌ Unformatted SQL
select u.id, u.name, u.email, count(o.id) as order_count, sum(o.total) as total_spent from users u left join orders o on u.id = o.user_id where u.created_at >= '2025-01-01' and u.status = 'active' group by u.id, u.name, u.email having count(o.id) > 5 order by total_spent desc limit 50;
✅ Formatted SQL
SELECT u.id, u.name, u.email, COUNT(o.id) AS order_count, SUM(o.total) AS total_spent FROM users u LEFT JOIN orders o ON u.id = o.user_id WHERE u.created_at >= '2025-01-01' AND u.status = 'active' GROUP BY u.id, u.name, u.email HAVING COUNT(o.id) > 5 ORDER BY total_spent DESC LIMIT 50;

SQL Formatting Best Practices
1. Uppercase SQL Keywords
Write SELECT, FROM, WHERE, JOIN in uppercase to visually separate them from table and column names. Our formatter does this automatically.
2. One Column Per Line in SELECT
List each selected column on its own line for easier scanning, commenting, and version control diffs.
3. Indent JOINs and Subqueries
Indent JOIN clauses and nested subqueries to show the logical structure of your query at a glance.
4. Use Table Aliases
Short, meaningful aliases (e.g., u for users) keep queries concise, especially with multiple JOINs.
Frequently Asked Questions
What does the SQL formatter do?
The SQL formatter takes messy, unformatted SQL queries and reformats them with proper indentation, keyword uppercasing, and logical line breaks. It makes complex queries with JOINs, subqueries, and CASE expressions easy to read and debug. It can also minify SQL into a single line for embedding in code.
Which SQL dialects are supported?
The formatter uses standard ANSI SQL keywords that work across all major databases: MySQL, PostgreSQL, SQLite, SQL Server (T-SQL), Oracle, MariaDB, and CockroachDB. Dialect-specific syntax is preserved during formatting — the tool focuses on universal keywords like SELECT, FROM, WHERE, JOIN, GROUP BY, and ORDER BY.
Is my SQL data secure?
Yes. All formatting happens entirely in your browser using client-side JavaScript. Your SQL queries — including those containing table names, column names, and WHERE conditions — are never transmitted to any server. This makes it safe for production queries and proprietary database schemas.
Can I format complex queries with subqueries and CTEs?
Yes! The formatter properly indents nested subqueries, Common Table Expressions (WITH/AS), CASE/WHEN expressions, UNION/INTERSECT/EXCEPT blocks, and window functions. Each level of nesting gets additional indentation for clarity.
What is the difference between beautify and minify?
Beautify adds proper indentation, line breaks, and uppercases SQL keywords to make queries readable. Minify removes all unnecessary whitespace and compresses the query into a single line — useful for embedding SQL in application code, reducing log size, or preparing queries for APIs.
Does it support syntax highlighting?
Yes. The formatted output uses color coding: SQL keywords in cyan, string literals in green, numbers in orange, comments in gray, and identifiers (table/column names) in white. This makes it much easier to scan and understand complex queries.
