What is SQL beautification?

SQL beautification (also called formatting or pretty-printing) reformats a SQL query with consistent indentation, line breaks, and keyword casing to make it easier to read and maintain.

Does formatting change the meaning of my SQL?

Formatting only changes whitespace and capitalisation. It does not alter the logic, execution plan, or result of the query.

Is my SQL sent to a server?

All processing runs in your browser using JavaScript. Our servers are not involved at any point.

Which SQL dialects are supported?

Standard SQL, MySQL, PostgreSQL, and T-SQL (Microsoft SQL Server). Select the appropriate dialect to get formatting that matches your database's conventions.

SQL beautifier

Paste a SQL query and get a cleanly indented, readable version instantly. Choose your SQL dialect to match the formatting conventions of your database.

SQL input

Formatting runs entirely in your browser.

How it works

The tool uses the sql-formatter library, a dialect-aware SQL pretty-printer that runs entirely in your browser. It parses your query and re-emits it with consistent indentation and capitalisation.

Example

Input

select u.id, u.name, count(o.id) as orders from users u left join orders o on o.user_id = u.id where u.active = 1 group by u.id, u.name order by orders desc

Formatted

SELECT
  u.id,
  u.name,
  count(o.id) AS orders
FROM
  users u
  LEFT JOIN orders o ON o.user_id = u.id
WHERE
  u.active = 1
GROUP BY
  u.id,
  u.name
ORDER BY
  orders DESC

Processing runs in your browser

All formatting happens locally in your browser tab. Our servers are not involved at any point.
