Beautify and standardize your SQL queries. Transform messy code into clean, readable SQL with customizable formatting options.
Transform messy, unreadable SQL queries into clean, standardized code instantly. Our advanced SQL formatter supports multiple dialects and customizable styling options.
Our formatter doesn't just indent code; it understands SQL structure. It properly handles complex nested queries, JOIN clauses, subqueries, and window functions, ensuring your code structure reflects its logical flow.
Whether you're using PostgreSQL, MySQL, SQLite, or Standard SQL, our tool adapts its formatting rules to match your specific database dialect, preserving dialect-specific syntax and keywords.
Structured Query Language (SQL) is the backbone of modern data interaction. However, as queries grow in complexity—spanning hundreds of lines with multiple `JOIN`s, subqueries, and window functions—readability becomes a critical challenge. Our SQL Formatter is designed to transform messy, unreadable code into a clean, standardized format instantly.
Formatting is not just about aesthetics; it is about code quality and maintainability.
SQL is not a monolith. Different databases have different keywords and syntax rules. Our tool supports:
There are two main schools of thought in SQL indentation, and our tool lets you verify which one suits your team best (currently defaulting to standard Block style).
Keywords are left-aligned. Columns and conditions are indented. This is the most common style for readability.
SELECT
id,
name
FROM
users
WHERE
active = 1Keywords and columns form a "river" of whitespace down the middle. Visually pleasing but harder to maintain.
SELECT id, name FROM users WHERE active = 1
Beyond using a tool, adopting these habits will make you a better SQL developer:
SELECT, WHERE, AS in uppercase. This makes the structure of the query immediately visible.Under the hood, this tool acts as a compiler frontend.
Absolutely. This SQL formatter runs 100% on the client side (in your browser). We do not have a backend server that receives your SQL queries. You can even disconnect from the internet and the tool will still work. Secure your sensitive business logic without worry.
The formatter creates a "best effort" format. If your SQL syntax is invalid (e.g., missing keywords), it might try to format it anyway or leave it as is. For strict checking, use our Syntax Validator first.
Yes! The tool excels at handling nested structures. It will recursively indent subqueries (queries inside parenthesis) so you can clearly see the data flow from the inner-most query to the outer result.
Simply paste the full `CREATE PROCEDURE` or `CREATE FUNCTION` block. The formatter recognizes procedural blocks (BEGIN/END) and indents the logic inside them appropriately.
