Frequently Asked Questions
Why format SQL queries?
Formatted SQL is easier to read, debug, and maintain. Proper indentation helps visualize the query structure, making it easier to spot errors and understand complex joins or subqueries.
Does this validate my SQL?
This tool focuses on formatting, not validation. It will format the SQL you provide but won't check if it's syntactically correct or will execute successfully.
Are my queries stored or sent to a server?
No. All formatting happens in your browser using JavaScript. Your SQL queries never leave your device.
