SQL Formatter & Beautifier
Free online SQL formatter and beautifier. Format SQL queries with customizable indentation, keyword casing, and dialect support for MySQL, PostgreSQL, SQL Server, Oracle, SQLite.
What is SQL formatting?
SQL formatting is the process of restructuring SQL code to improve readability by applying consistent indentation, line breaks, keyword casing, and alignment. Well-formatted SQL is easier to read, debug, and maintain.
What SQL dialects does this formatter support?
This SQL formatter supports standard SQL syntax and works with MySQL, PostgreSQL, SQL Server (T-SQL), Oracle (PL/SQL), SQLite, and other major database systems.
Can I customize the indentation style?
Yes, you can choose between spaces or tabs and set the indentation width (e.g., 2, 4, or 8 spaces) to match your team's coding standards.
Can I control keyword casing?
Yes, the formatter supports uppercase, lowercase, and title case for SQL keywords like SELECT, FROM, WHERE, allowing you to follow your organization's style guide.
Is my SQL data safe?
Absolutely. All SQL formatting is performed entirely in your browser using client-side JavaScript. No data is ever sent to any server, ensuring complete privacy and security.
Can this formatter minify SQL?
Yes, in addition to beautifying SQL, the tool can also compress SQL into a single line by removing unnecessary whitespace, which is useful for embedding queries in code.
Does it handle complex nested queries?
Yes, the formatter correctly handles deeply nested subqueries, JOINs, CASE expressions, UNION statements, CTEs (WITH clauses), and other complex SQL constructs.
What is the difference between SQL formatting and SQL validation?
SQL formatting only adjusts the visual presentation of your code without changing its logic. SQL validation checks whether the syntax is correct for a specific database engine. This tool focuses on formatting only.
Does it support stored procedures and functions?
Yes, the formatter handles CREATE PROCEDURE, CREATE FUNCTION, BEGIN...END blocks, DECLARE statements, and other procedural SQL extensions.
Can I use this tool offline?
Yes, once the page is loaded, all formatting operations run locally in your browser. You don't need an active internet connection to format SQL queries.
Is there a limit on SQL query length?
There is no hard limit. The formatter can handle queries of any length, though very large scripts (thousands of lines) may take a moment to process depending on your device's performance.
Why should I format my SQL code?
Formatted SQL improves code readability, makes debugging faster, facilitates team collaboration, helps spot syntax errors quickly, and makes code reviews more efficient. Consistent formatting is a hallmark of professional database development.
How to Use SQL Formatter & Beautifier
Turn messy, minified SQL into clean, readable queries right in your browser. Paste a statement, choose your dialect — from MySQL and PostgreSQL to BigQuery and Snowflake — and format it with your preferred indentation and keyword casing. Nothing leaves the page.
- Paste your query into the editor — the placeholder shows an example: SELECT * FROM users WHERE id = 1.
- Select your dialect from the list: Standard SQL, MySQL, PostgreSQL, SQL Server, MariaDB, BigQuery, Snowflake, DB2, PL/SQL, Hive, Redshift or Spark SQL.
- Adjust the indentation settings so nested SELECTs and JOINs line up the way your team reads them.
- Choose uppercase or lowercase keyword casing to match your in-house SQL style guide.
- Run the formatter and copy the beautified query back into your IDE, migration or code review.
Pick the right dialect before formatting — dialect-specific syntax such as PL/SQL blocks and T-SQL variables formats differently from standard SQL.
