SQL Formatter Online — Format and Beautify SQL Queries Instantly

A SQL query written in one long line is technically valid but completely unreadable. Whether it came from an ORM, a log file, a minified source, or a colleague who doesn't believe in indentation — unformatted SQL slows down every developer who has to read or debug it.

The SQL Formatter cleans it up instantly. Paste your SQL, get properly indented, keyword-highlighted, readable output in one click.

What SQL Formatting Does

SQL formatting restructures a query with consistent indentation, line breaks, and keyword capitalisation so the logic is immediately visible.

Before formatting:

select u.id,u.name,o.total from users u inner join orders o on u.id=o.user_id where o.total>1000 and u.active=true order by o.total desc limit 10

After formatting:

SELECT
  u.id,
  u.name,
  o.total
FROM users u
INNER JOIN orders o ON u.id = o.user_id
WHERE
  o.total > 1000
  AND u.active = TRUE
ORDER BY o.total DESC
LIMIT 10

Same query. Completely different readability.

When You Need a SQL Formatter

Debugging complex queries — when a query is failing and you need to understand the logic, formatting it first makes the problem visible immediately.

Code reviews — reviewing a pull request with unformatted SQL embedded in code is painful. Format it first to review the logic properly.

Reading ORM output — ORMs like SQLAlchemy, Prisma, and ActiveRecord generate valid but unformatted SQL. When you need to see exactly what query is being executed, formatting it makes it readable.

Log file analysis — database slow query logs capture SQL as single lines. Formatting them makes analysis practical.

Documentation — writing SQL in technical docs or comments requires clean formatting for readability.

Learning SQL — reading formatted queries is one of the fastest ways to understand SQL patterns and syntax.

Supports Multiple SQL Dialects

The formatter handles the most common SQL dialects:

• Standard SQL — SELECT, INSERT, UPDATE, DELETE
• PostgreSQL — including Neon, Supabase, and standard Postgres syntax
• MySQL — including MariaDB
• SQLite — lightweight database syntax
• T-SQL — Microsoft SQL Server

Most standard SQL syntax formats correctly regardless of dialect.

SQL Formatter for Neon PostgreSQL Users

If you're using Neon PostgreSQL — the serverless Postgres database — you likely write SQL queries directly. The formatter is useful for cleaning up hand-written queries before running them and for reading the output of EXPLAIN plans which are often returned as unformatted text.
