People also ask
Which SQL dialects are supported?
The formatter supports Standard SQL, MySQL, PostgreSQL, SQL Server (T-SQL), Oracle PL/SQL, and SQLite syntax.
Does it uppercase SQL keywords?
By default, keywords like SELECT, FROM, WHERE, and JOIN are uppercased. You can change this to lowercase or leave them as-is.
Does formatting change the query behavior?
No, formatting only changes whitespace and casing. The query logic and results remain identical.
Can it handle complex queries with CTEs and subqueries?
Yes, Common Table Expressions (WITH clauses), subqueries, CASE statements, and multi-table JOINs are all formatted with proper nesting.
Is this tool free?
Yes, the SQL Formatter is completely free with no usage limits.

- Select the SQL dialect (MySQL, PostgreSQL, T-SQL, PL/SQL, or Standard SQL).
- Choose formatting options — keyword case, indentation size, and line break style.
- Click 'Format' and copy the beautifully indented SQL query.
Why use this tool?
Complex SQL queries with subqueries, joins, and CTEs become unreadable when written on a single line or with inconsistent formatting. This SQL beautifier makes queries readable and maintainable, which is critical for code reviews and debugging.

SQL Formatter — In-Depth Guide
SQL formatting transforms messy, compressed, single-line queries into properly indented, logically structured, and highly readable code that is far easier to work with. Database administrators, backend developers, and data engineers work with complex multi-table queries every single day, and consistent professional formatting makes those queries significantly easier to review, debug, optimize, and maintain over time. Well-formatted SQL with clear hierarchical indentation immediately reveals the logical structure of joins, subqueries, and filtering conditions at a glance.
Code review processes and team collaboration workflows benefit enormously from consistently formatted SQL applied across the entire development team and codebase. When all team members consistently follow the same formatting conventions, style guidelines, and layout patterns, pull request diffs focus exclusively on meaningful logical and functional changes rather than distracting and irrelevant whitespace and formatting differences. Establish a clear team standard for keyword capitalization, indentation depth, and line break placement, then use the formatter to enforce it.
Students learning SQL and database querying find well-formatted queries dramatically easier to understand, analyze, and learn from than dense single-line or inconsistently indented alternatives. Seeing each clause clearly displayed on its own line with proper hierarchical indentation helps beginners quickly recognize query structure, understand the relationships between different clauses, and learn proper SQL syntax patterns effectively. Format all example queries before studying them to meaningfully accelerate your SQL learning journey and build professional habits.
Data analysts and business intelligence professionals writing ad-hoc exploratory queries in database tools like DBeaver, pgAdmin, DataGrip, or BigQuery console often draft quick investigative queries without applying any consistent formatting or style conventions. Before saving these valuable and potentially reusable queries to a shared team repository, documentation wiki, or analysis playbook, run them through the formatter for consistent readable style. Well-formatted saved queries become valuable reusable analytical assets that benefit the entire team.
