Frequently Asked Questions
What does an SQL formatter do?
An SQL formatter takes compressed or messy SQL queries and reformats them with proper indentation, line breaks, and spacing for better readability.
Which SQL dialects are supported?
The formatter supports standard SQL and works well with MySQL, PostgreSQL, SQL Server, Oracle, and SQLite queries.
Is my SQL query uploaded to a server?
No. All formatting happens locally in your browser using JavaScript. Your SQL queries never leave your device.
Can it format complex queries?
Yes! The formatter handles SELECT, INSERT, UPDATE, DELETE, JOINs, subqueries, CTEs, and other SQL constructs.
Does it validate SQL syntax?
The formatter focuses on formatting, not validation. It will format what you provide but won't check for syntax errors.
