SQL Formatter & Beautifier

A SQL formatter, also called a SQL beautifier, turns long, messy queries into clean, readable code with proper line breaks and indentation. Paste your query, pick your dialect and get a neat result in one click. It works with MySQL, PostgreSQL, SQL Server, Oracle and SQLite, and it runs in your browser.

How to Format SQL Online

Paste your SQL query into the input box.
Choose your SQL dialect, indentation and keyword case.
Click Format SQL to beautify the query, or Minify SQL to compress it into one line.
Copy the result or download it as a .sql file.

About This SQL Formatter

This SQL formatter turns long, unreadable queries into clean code with proper line breaks and indentation. Keywords like SELECT, FROM, JOIN, WHERE and GROUP BY start on their own lines, columns are listed one per line, and nested subqueries are indented so you can follow the logic at a glance.

It is useful for developers reviewing code, data analysts cleaning up reports, students learning SQL, and anyone who has copied a one-line query from a log file or an ORM and needs to read it.

The tool formats only the text of your query. It does not connect to a database and does not run your SQL.

Example: Before and After

Input

select u.id,u.name,count(o.id) as total_orders from users u left join orders o on o.user_id=u.id where u.status='active' and o.created_at>='2026-01-01' group by u.id,u.name having count(o.id)>5 order by total_orders desc limit 10;

Formatted output

SELECT
  u.id,
  u.name,
  COUNT(o.id) AS total_orders
FROM
  users u
  LEFT JOIN orders o ON o.user_id = u.id
WHERE
  u.status = 'active'
  AND o.created_at >= '2026-01-01'
GROUP BY
  u.id,
  u.name
HAVING
  COUNT(o.id) > 5
ORDER BY
  total_orders DESC
LIMIT
  10;

Features

Multiple dialects: MySQL, PostgreSQL, SQL Server, Oracle, SQLite and standard SQL.
Format and minify: Beautify for reading, or compress to a single line for config files and scripts.
Keyword case control: Convert keywords to uppercase or lowercase, or keep them as written.
Custom indentation: 2 spaces, 4 spaces or tabs, to match your team's style.
Copy and download: One click to copy, or save the result as a .sql file.
Private by design: The tool runs in your browser using JavaScript, and your query is not sent to our server.

Supported SQL Dialects

Dialect	Database	Good for
Standard SQL	Any	Generic queries that do not use database-specific syntax
MySQL	MySQL, MariaDB	Queries with backticks, `LIMIT` and MySQL functions
PostgreSQL	PostgreSQL	Queries with `::` casts, `ILIKE` and CTEs
SQL Server (T-SQL)	Microsoft SQL Server	Queries with `TOP`, square brackets and T-SQL statements
Oracle (PL/SQL)	Oracle Database	Queries with Oracle functions and PL/SQL blocks
SQLite	SQLite	Queries for mobile apps and small local databases

Formatting Options

Option	Choices	What it does
SQL dialect	Standard SQL, MySQL, PostgreSQL, SQL Server, Oracle, SQLite	Applies the right keywords and syntax rules for your database
Indentation	2 spaces, 4 spaces, Tab	Sets how far nested lines are indented
Keyword case	UPPERCASE, lowercase, Preserve	Changes the case of SQL keywords only, not table or column names
Format SQL	Button	Beautifies the query for reading
Minify SQL	Button	Removes extra spaces and line breaks into a compact query

Why Format SQL?

Easier to read: Long queries with many joins and conditions become much easier to follow.
Faster debugging: Missing commas, wrong joins and misplaced conditions are easier to spot.
Cleaner code reviews: A consistent style means reviewers focus on logic, not layout.
Better teamwork: Everyone on the team reads the same layout, whichever editor they use.

Common Uses

Cleaning up queries copied from application logs or ORM debug output
Making stored procedures and reports readable before sharing
Preparing SQL for documentation, tutorials or interviews
Minifying SQL before adding it to code or configuration files

Frequently Asked Questions

1. What is a SQL formatter?

A SQL formatter is a tool that rearranges the text of a SQL query into a clean, consistent layout. It adds line breaks and indentation and can change keyword case, so the query is easier to read. It does not change what the query does.

2. Does formatting change the result of my query?

No. Formatting changes only whitespace and, if you choose, the case of keywords. Your query returns the same results. As a good habit, still run important queries in a test environment after copying them back.

3. Is my SQL sent to your server?

No. This tool runs in your browser, and your query is not sent to our server. Still, avoid pasting real passwords, API keys or sensitive production data into any online tool.

4. Which SQL dialects does the formatter support?

You can choose standard SQL, MySQL, PostgreSQL, SQL Server (T-SQL), Oracle (PL/SQL) or SQLite. Picking the right dialect gives better results for dialect-specific syntax.

5. Can I minify SQL with this tool?

Yes. Use the Minify SQL button to remove extra spaces and line breaks and get a compact single-line query.

6. Does this tool check my SQL for errors?

It is a formatter, not a database validator. It does not check whether tables and columns exist or whether the query will run. If the query has a serious syntax problem, the tool may show an error or format it imperfectly.

7. Can I format more than one query at a time?

Yes. Paste multiple statements separated by semicolons and the tool formats each one.

8. Is this SQL beautifier free?

Yes. It is completely free, with no signup and no usage limits.

9. Does it work on mobile?

Yes. The page is light and works on phones and tablets.
