Frequently Asked Questions
Does the SQL formatter support all SQL dialects?
It handles standard SQL (ANSI) and most of MySQL, PostgreSQL, and SQL Server syntax. Dialect-specific functions are formatted but not validated.
Will formatting change my SQL logic?
No. Only whitespace and capitalization are changed — your query logic, table names, and conditions are untouched.
Is this SQL beautifier free?
Yes. Completely free with no account required.
