SQL Formatter & Beautifier — Readable Queries Instantly
Well-formatted SQL is easier to read, debug, and maintain. This formatter adds consistent indentation, aligns keywords, and breaks long queries into readable lines. Paste minified or messy SQL below — formatting runs locally in your browser.
What is SQL formatting?
SQL formatting applies consistent indentation, line breaks, and keyword alignment to database queries. While SQL engines ignore whitespace, readable formatting makes queries easier for humans to understand, review, and debug.
Why Use This Tool
- Code review — Make complex queries readable for team review.
- Debug queries — Spot syntax errors and logic issues in formatted code.
- Documentation — Include readable SQL in docs, tickets, or tutorials.
- Compare versions — Format both versions before comparing changes. Compare text →
- Minify for logging — Compact SQL to a single line for log files.
- Learning SQL — See query structure clearly when learning syntax.
Tips
- Format SQL before code reviews for easier reading.
- Use consistent indentation (2 or 4 spaces) across your project.
- Uppercase keywords (SELECT, FROM) is optional but common.
- Format both versions before comparing changes in diffs.
- Comments are preserved during formatting.

Worked Examples
Simple SELECT
SELECT id, name, email FROM users WHERE active = 1;
SELECT id, name, email FROM users WHERE active = 1;
JOIN query
SELECT u.name, o.total FROM users u INNER JOIN orders o ON u.id = o.user_id WHERE o.status = 'completed';
SELECT u.name, o.total FROM users u INNER JOIN orders o ON u.id = o.user_id WHERE o.status = 'completed';
INSERT statement
INSERT INTO users (name, email, created_at) VALUES ('John', 'john@example.com', NOW());INSERT INTO
users (name, email, created_at)
VALUES
('John', 'john@example.com', NOW());Subquery
SELECT * FROM orders WHERE user_id IN (SELECT id FROM users WHERE status = 'active');

Frequently Asked Questions
How do I format SQL online?
Paste your SQL query into this tool and click Format. The formatter adds proper indentation, aligns keywords, and breaks the query into readable lines — all in your browser.
Does formatting change how SQL executes?
No. SQL engines ignore whitespace. Formatting only affects how humans read the code; the query runs identically.
What SQL dialects are supported?
This formatter works with standard SQL syntax including SELECT, INSERT, UPDATE, DELETE, JOINs, subqueries, CTEs, and most common keywords across PostgreSQL, MySQL, SQL Server, and SQLite.
Can I minify SQL to a single line?
Use the Minify option to remove unnecessary whitespace and put the query on fewer lines for logging or compact storage.
Should I uppercase SQL keywords?
It's a style preference. Some teams use uppercase (SELECT, FROM, WHERE) for visibility; others use lowercase. Consistency within a project matters most.
Does this SQL formatter upload my queries?
No. Formatting runs entirely in your browser. Your SQL never leaves your device.
