How do I format a SQL query online?

Paste the query into the input box and the beautified version appears instantly, with each clause on its own line and nested logic indented. Copy it with one click.

Which SQL dialects are supported?

The formatter uses standard SQL grammar, which covers the shared syntax of PostgreSQL, MySQL, SQL Server, and SQLite for everyday queries. Highly dialect-specific syntax may occasionally format imperfectly.

Does the formatter change keyword casing?

Yes — reserved SQL keywords are uppercased for consistency and readability, while your table and column identifiers are preserved exactly as written.

Can it format an entire multi-statement script?

Yes. Paste several statements separated by semicolons and each is formatted in place, so you can beautify a whole migration or seed file at once.

Does formatting change what the query does?

No. Formatting only changes whitespace, line breaks, and layout — the statement's semantics are untouched.

Is my SQL kept private?

Yes. Formatting runs entirely in your browser; queries, table names, and embedded values are never transmitted to a server.

SQL Formatter and Beautifier Online

This free SQL formatter turns long, single-line, or inconsistently written SQL queries into cleanly indented, readable statements. Keywords, clauses, and nested subqueries are laid out on separate lines so you can review JOIN logic, debug WHERE conditions, and share queries with teammates without squinting.

It handles standard SQL — SELECT, INSERT, UPDATE, DELETE, DDL statements, joins, CTEs, and subqueries — and formats everything locally in your browser, so proprietary queries and schema names never leave your machine.

How to use SQL Formatter

Paste your SQL query or script into the input box.
The formatted SQL appears automatically with keywords and clauses on separate indented lines.
Copy the result with the copy button and paste it into your editor, migration file, or documentation.

Why format SQL?

SQL generated by ORMs, logged by applications, or written in a hurry often arrives as one enormous line. Formatting exposes the query's structure — which tables are joined, in what order conditions apply, and where subqueries begin and end — which is essential for code review, query optimization, and onboarding teammates. Consistent formatting also produces cleaner diffs in version control.

SELECT
  users.id,
  users.email,
  COUNT(orders.id) AS order_count
FROM
  users
  LEFT JOIN orders ON orders.user_id = users.id
WHERE
  users.active = TRUE
GROUP BY
  users.id,
  users.email
ORDER BY
  order_count DESC;

A formatted query: one clause per line, indented join and conditions.

Keyword casing, dialects, and options

SQL keywords are case-insensitive, but a consistent convention makes queries far easier to scan. This formatter uppercases reserved keywords (SELECT, FROM, WHERE, JOIN, GROUP BY) while leaving your identifiers — table and column names — untouched, then indents each clause and lines up JOINs and conditions.

It follows standard SQL grammar, which covers the everyday syntax shared by PostgreSQL, MySQL, SQL Server, and SQLite: SELECT, INSERT, UPDATE, and DELETE statements, JOINs, common table expressions (WITH), subqueries, and DDL. Dialect-specific extensions are formatted on a best-effort basis.

Common scenarios

Reach for the formatter when you copy a one-line query out of an ORM debug log, review a teammate's pull request full of dense SQL, clean up a migration before committing it, or paste an example from documentation that lost its line breaks. In each case, a single pass turns an unreadable string into a query whose logic you can follow from top to bottom.

Related terminology

Clause: A building block of a SQL statement such as SELECT, FROM, WHERE, GROUP BY, or ORDER BY, each starting on its own line in formatted output.
CTE (Common Table Expression): A named subquery introduced with WITH that makes complex queries readable by breaking them into steps.
Subquery: A query nested inside another query; formatting indents subqueries so their scope is visually clear.
DDL / DML: Data Definition Language (CREATE, ALTER) defines schema; Data Manipulation Language (SELECT, INSERT, UPDATE, DELETE) works with data.
