SQL Formatter

What is an SQL formatter?

An SQL formatter, or SQL beautifier, turns hard-to-read queries into consistently indented, clause-aligned code. Instead of scanning a single-line query for the JOIN conditions, you can read the statement top-to-bottom the same way you read a well-formatted program.

Before

SELECT u.id,u.name,COUNT(o.id) AS cnt FROM users u LEFT JOIN orders o ON o.user_id=u.id WHERE u.active=1 GROUP BY u.id,u.name HAVING COUNT(o.id)>0 ORDER BY cnt DESC;

After

SELECT
  u.id,
  u.name,
  COUNT(o.id) AS cnt
FROM users u
LEFT JOIN orders o ON o.user_id = u.id
WHERE u.active = 1
GROUP BY u.id, u.name
HAVING COUNT(o.id) > 0
ORDER BY cnt DESC;

Why dialect matters

Identifiers are quoted differently per database: [orders] for SQL Server, `orders` for MySQL and BigQuery, "orders" for PostgreSQL. The dialect setting keeps those conventions intact while normalizing everything else.

FAQ

What does an SQL formatter do?+

An SQL formatter (also called an SQL beautifier) rewrites the whitespace of a query — line breaks and indentation — so that SELECT, FROM, WHERE, JOIN, and GROUP BY clauses align in a readable way. It never changes the meaning of the query.

Why does the formatter ask for a SQL dialect?+

SQL dialects differ in syntax — for example BigQuery uses backticks for identifiers, SQL Server uses square brackets, and Oracle uses its own PL/SQL blocks. Choosing the right dialect lets the formatter keep your syntax intact and format it correctly.

Will formatting break my query?+

No. Formatting only changes whitespace and optional keyword casing. String literals, comments, and the order of your statements are preserved exactly.

Can it format multiple statements at once?+

Yes. Paste multiple statements (for example a CREATE TABLE followed by an INSERT) and the formatter keeps each statement separated and readable.
