Does this SQL formatter execute queries on my database?

No. The tool is purely a syntax formatter running in your browser. It does not connect to any database or transmit your table structures anywhere.

Does it support complex subqueries and window functions?

Yes. Subqueries, CTEs (WITH clauses), window functions, and nested joins are properly indented with matching bracket hierarchy.

The SQL Formatter beautifies and indents unformatted SQL queries into clean, standard, human-readable code.

SELECT id, name 
FROM users 
WHERE active = 1 
ORDER BY created_at DESC
