Frequently Asked Questions
Does it support different SQL dialects?
Yes! You can choose between MySQL, PostgreSQL, SQL Server (T-SQL), SQLite, and standard ANSI SQL formats from the dialect selector at the top of the tool.
Why should I format SQL queries?
Formatted SQL is easier to read, debug, and review — especially for complex queries with multiple JOINs, subqueries, or CTEs. Consistent formatting also helps in code reviews and documentation.
Does formatting change my query's behavior?
No — SQL formatting only affects whitespace and capitalization, never the logic or execution of the query. Your formatted SQL will produce identical results to the original.
Is my database code safe?
100%. All formatting happens in your browser's local memory. Your queries are never sent to a server, logged, or stored anywhere.
Can I minify SQL?
Yes. Switch to the "Minify SQL" tab to strip all whitespace and comments. This produces compact SQL suitable for use in application configuration or code strings.
Does it work with stored procedures or long scripts?
Yes — paste stored procedures, triggers, or full SQL scripts (up to 1MB). The formatter handles them accordingly without any issues.
Is it free?
Yes, completely free with no limits on query length or frequency. No account or registration required. No premium tiers.
Does it work on mobile?
Yes, the SQL Formatter is fully responsive and works on smartphones, tablets, and desktops.
