SQL Formatter
Paste messy SQL, get it formatted, beautified, and syntax-highlighted instantly.
What is SQL Formatting?
SQL formatting (also called SQL beautifying or SQL pretty printing) is the process of restructuring raw SQL queries into a clean, readable layout. Database queries written on a single line or with inconsistent spacing are difficult to read, debug, and review. A SQL formatter automatically adds proper indentation, line breaks, and keyword casing so your queries are clear at a glance.
Why Format SQL?
Whether you're working with simple SELECT statements or complex multi-table JOINs with subqueries, properly formatted SQL dramatically improves your workflow:
- Readability: Instantly see the structure of JOINs, WHERE clauses, subqueries, and CTEs.
- Debugging: Spot missing conditions, incorrect aliases, and logic errors faster.
- Code review: Formatted SQL makes pull requests and peer reviews much more efficient.
- Consistency: Enforce a uniform style across your team's SQL codebase.
Supported SQL Constructs
| Construct | Description | Example |
|---|---|---|
| SELECT / FROM / WHERE | Basic query structure | SELECT name FROM users WHERE active = 1 |
| JOIN | Inner, Left, Right, Full, Cross joins | LEFT JOIN orders ON users.id = orders.user_id |
| Subqueries | Nested SELECT statements | WHERE id IN (SELECT user_id FROM orders) |
| CTE (WITH) | Common Table Expressions | WITH active_users AS (SELECT ...) |
| CASE | Conditional expressions | CASE WHEN status = 1 THEN 'Active' END |
| INSERT / UPDATE / DELETE | Data manipulation statements | INSERT INTO users (name) VALUES ('Gab') |
| CREATE / ALTER | DDL statements | CREATE TABLE users (id INT PRIMARY KEY) |
Frequently Asked Questions
What is a SQL formatter?
A SQL formatter is a tool that takes raw or poorly formatted SQL queries and restructures them with proper indentation, line breaks, and consistent keyword casing. This makes complex queries much easier to read, debug, and maintain.
How does a SQL beautifier work?
A SQL beautifier parses your SQL statement into its component parts (keywords, identifiers, operators, literals) and then reconstructs the query with consistent formatting rules — such as placing each clause on its own line, indenting subqueries, and uppercasing reserved keywords like SELECT, FROM, and WHERE.
Can I format SQL online for free?
Yes. Online SQL formatters like this one let you paste any SQL query and instantly get a beautified version with proper indentation and syntax highlighting — completely free, with no sign-up required. Everything runs in your browser so your queries never leave your device.
What SQL statements are supported?
This formatter supports all major SQL statement types including SELECT, INSERT, UPDATE, DELETE, CREATE TABLE, ALTER TABLE, DROP, JOIN operations (INNER, LEFT, RIGHT, FULL, CROSS), subqueries, CASE expressions, Common Table Expressions (CTEs with WITH), UNION, GROUP BY, HAVING, ORDER BY, and more.
What is SQL pretty print?
SQL pretty print refers to formatting a SQL query so that it is visually structured and easy to read. This typically involves adding line breaks before major clauses (SELECT, FROM, WHERE, JOIN), indenting column lists and conditions, and optionally uppercasing SQL keywords for visual distinction.
