Overview
The SQL Formatter is a powerful tool for beautifying and organizing SQL queries. It automatically adds proper indentation, line breaks and consistent keyword casing to make your SQL more readable and maintainable.
When to Use SQL Formatter
- Cleanup Minified Queries: Transform one-line queries into readable, structured SQL
- Code Reviews: Format queries before sharing with team members
- Documentation: Create clean, professional SQL examples for docs (similar to our JSON Formatter for JSON)
- Debugging: Make complex queries easier to understand and troubleshoot
- Learning: Study well-formatted SQL to understand query structure
- Standardization: Enforce consistent SQL style across projects
How to Use
- 1. Set Options: Choose your preferred indentation (2, 4 or 8 spaces) and keyword casing
- 2. Paste SQL: Enter or paste your SQL query in the input area
- 3. Format: Click "Format SQL" to beautify your query
- 4. Copy: Use the "Copy" button to copy the formatted SQL to your clipboard

Examples
Basic SELECT Query
Before:
select id,name,email from users where status='active' order by created_at descAfter:
SELECT id,
name,
email
FROM users
WHERE status='active'
ORDER BY created_at DESCJOIN Query
Before:
select u.name,o.total from users u inner join orders o on u.id=o.user_id where o.status='completed'After:
SELECT u.name,
o.total
FROM users u
INNER JOIN orders o
ON u.id=o.user_id
WHERE o.status='completed'Complex Aggregation
Before:
select category,count(*) as total,avg(price) as avg_price from products where active=true group by category having count(*)>5 order by total descAfter:
SELECT category,
count(*) AS total,
avg(price) AS avg_price
FROM products
WHERE active=true
GROUP BY category
HAVING count(*)>5
ORDER BY total DESCINSERT Statement
Before:
insert into users (name,email,status) values ('John Doe','john@example.com','active')After:
INSERT INTO users (name,
email,
status)
VALUES
('John Doe',
'john@example.com',
'active')Use Cases
