Free Online SQL Formatter

Format SQL queries into a clean, readable layout with consistent indentation and line breaks. This free SQL beautifier helps developers review SELECT statements, joins, filters, subqueries and database scripts more comfortably.

Format your SQL query

Paste a SQL query and select Format SQL.

This tool formats SQL text in your browser. It does not connect to a database or execute your query. Avoid entering passwords, credentials or other secrets into online tools.

What is a SQL formatter?

A SQL formatter, also known as a SQL beautifier, organizes SQL statements using indentation, line breaks and consistent keyword casing. It makes lengthy queries easier to read, debug, review and maintain. Formatting improves presentation but does not prove that a query is valid, secure or efficient.

How to format SQL online

  1. Paste your SQL statement into the editor.
  2. Select Format SQL to arrange clauses and indentation.
  3. Select Compact SQL to reduce unnecessary whitespace.
  4. Select Copy SQL to copy the current editor contents.
  5. Review the query in your database client before running it.

Benefits of readable SQL queries

Consistent formatting can make SELECT lists, JOIN conditions, WHERE filters, GROUP BY clauses, ordering and nested queries easier to inspect. Readable SQL also helps teams review changes and maintain shared database scripts.

SQL dialects and compatibility

SQL Server, PostgreSQL, MySQL and SQLite have dialect-specific syntax. A formatter can improve the layout of common SQL statements, but you should validate dialect-specific features using the database engine you use.

Frequently asked questions

Does this SQL formatter execute queries?

No. It formats SQL text only and does not connect to a database.

Does formatting validate SQL syntax?

Formatting is not a substitute for parsing or database validation. Test the query in the appropriate database environment before executing it.

Can I use this tool for SQL Server, MySQL and PostgreSQL?

You can use it to improve the readability of common SQL queries. Because dialects differ, always review specialized syntax after formatting.

Is the SQL formatter free?

Yes. The tool is available free of charge in a modern web browser.
