What is SQL formatting?

SQL formatting transforms messy or single-line SQL queries into well-indented, readable code with consistent keyword casing and proper line breaks. This makes complex queries much easier to understand and maintain.

Which SQL dialects does this tool support?

This sql formatter supports standard SQL syntax that works across most databases including MySQL, PostgreSQL, SQLite, SQL Server, and Oracle. It handles common clauses like SELECT, JOIN, WHERE, GROUP BY, and subqueries.

Does formatting change how my query runs?

No. SQL formatting only changes whitespace and letter casing. The query logic, execution plan, and results remain completely identical. It is purely a readability improvement.

Can I format stored procedures and complex queries?

Yes. The formatter handles complex SQL including nested subqueries, CTEs (WITH clauses), CASE statements, window functions, and multi-table joins with proper indentation.

Is my SQL data safe in this tool?

Yes. All formatting happens in your browser. Your SQL queries are never uploaded to any server, so your database schemas and data remain completely private.
