COMMON QUESTIONS

Frequently Asked Questions

Everything you need to know about the tool, privacy, and formatting options.

Is this SQL formatter free to use? +
Yes, completely free forever. There are no subscriptions, paywalls, daily limits, or account requirements.
Does it support MySQL, PostgreSQL, SQLite, and T-SQL? +
Yes. Select your preferred dialect from the toolbar dropdown. The formatter adapts keyword rules and syntax handling for MySQL, PostgreSQL, SQLite, Microsoft T-SQL, and Standard ANSI SQL.
Is my SQL query or database schema sent to any server? +
No. All SQL parsing and formatting executes 100% locally in your browser using JavaScript. No database query, table name, or data is ever uploaded or transmitted across the internet.
Can I format very large and complex SQL queries? +
Yes. Our client-side lexer and tokenizer can format queries with hundreds of lines, multiple JOINs, subqueries, and CTEs (Common Table Expressions) in a few milliseconds without any performance bottleneck.
What is the difference between SQL beautification and minification? +
Beautification adds clean line breaks, uppercase keywords, and structured indentation to make SQL easy to read and review. Minification strips all unnecessary whitespace and newlines into a compact single line suitable for codebases, migrations, and ORMs.
Can I customize indentation spacing? +
Yes, you can choose between 2 spaces, 4 spaces, or hard tabs in the toolbar before clicking Format.
How do I quickly copy the formatted SQL? +
Click the "Copy Output" button in the toolbar. A toast notification will confirm that the formatted SQL has been copied to your clipboard.
Does Redsite store or track any user queries? +
Never. Redsite operates under the strict principle of "Simple by Design. Private by Default." There are no analytics trackers, no backend database logging, and no cookies.
