A SQL formatter (also called a SQL beautifier or pretty printer) is a tool that automatically adds proper indentation, line breaks, and capitalization to SQL queries to make them more readable and maintainable. It transforms messy, single-line SQL into clean, well-structured code that's easy to understand and debug.
SQL formatting is essential for code reviews, documentation, and team collaboration. Well-formatted SQL makes it easier to spot errors, understand complex joins, identify performance issues, and maintain consistent coding standards across your database projects.
This SQL formatter runs entirely in your browser using JavaScript. Your queries never leave your device or get sent to any server, making it completely safe for production queries, sensitive data, or proprietary database schemas.
Format MySQL queries with support for MySQL-specific syntax like LIMIT, backtick identifiers, and MySQL functions.
Format PostgreSQL queries including CTEs, window functions, RETURNING clauses, and PostgreSQL-specific operators.
Format SQLite queries with support for SQLite syntax, including AUTOINCREMENT, PRAGMA statements, and SQLite functions.
Format T-SQL queries for Microsoft SQL Server, including stored procedures, triggers, and SQL Server-specific syntax.
Format Oracle PL/SQL queries with support for Oracle-specific features like DUAL table, CONNECT BY, and Oracle functions.
Format MariaDB queries with support for MariaDB-specific extensions and compatibility with MySQL syntax.
| Category | Keywords | Purpose |
|---|---|---|
| Data Query | SELECT, FROM, WHERE, JOIN | Retrieve data from tables |
| Data Manipulation | INSERT, UPDATE, DELETE | Modify table data |
| Data Definition | CREATE, ALTER, DROP | Define and modify table structure |
| Filtering | WHERE, HAVING, IN, LIKE | Filter query results |
| Aggregation | GROUP BY, COUNT, SUM, AVG | Aggregate and summarize data |
| Sorting | ORDER BY, ASC, DESC | Sort query results |
Copy your SQL query from your code editor, database tool, or application and paste it into the input field.
Choose your database dialect (MySQL, PostgreSQL, SQLite, etc.) for dialect-specific formatting. Standard SQL works for most queries.
Click the Format button to beautify your SQL. The formatted query appears in the output pane with proper indentation and line breaks.
Click Copy to copy the formatted SQL to your clipboard. Paste it back into your code, documentation, or database tool.
SQL formatting (or beautifying) adds proper indentation, line breaks, and capitalization to SQL queries to make them more readable. It helps developers understand complex queries, debug issues, and maintain consistent code style across teams.
This formatter supports Standard SQL, MySQL, PostgreSQL, SQLite, SQL Server, Oracle, and MariaDB. While the core SQL syntax is similar across databases, each has specific keywords and functions. Select your database dialect for best results.
This is primarily a formatter, not a validator. It will format valid SQL and attempt to format invalid SQL, but it won't catch all syntax errors. For validation, test your queries in your actual database environment.
Yes, this formatter handles SELECT, INSERT, UPDATE, DELETE, CREATE, ALTER, and other SQL statements. It works with subqueries, joins, CTEs, window functions, and most SQL constructs. Very complex stored procedures may require manual adjustment.
Absolutely. This tool runs entirely in your browser using JavaScript. Your SQL queries never leave your computer or get sent to any server. All formatting happens locally on your device, making it safe for production queries and sensitive data.
