FAQ

Q: Which SQL dialects are supported?
A: MySQL, PostgreSQL, SQLite, MariaDB, MS SQL Server (T-SQL), Oracle, BigQuery, and others. Select the matching dialect to ensure keywords and syntax are formatted correctly for your database.
Q: Does formatting change the meaning of my SQL?
A: No. The formatter only adjusts whitespace, line breaks, and keyword casing. The logical meaning and execution result of the query remain identical.
Q: Can I format SQL with subqueries or CTEs?
A: Yes. The formatter handles nested subqueries, CTEs (WITH clauses), JOINs, window functions, and most complex SQL constructs.
Q: Can I choose keyword casing (e.g. uppercase SELECT vs lowercase select)?
A: Yes. Common options are UPPERCASE, lowercase, or preserve-as-is. Check the options panel for the available casing settings.
Q: Does this tool send my SQL to a server?
A: No. All formatting is performed entirely in the browser. Your SQL is never sent to any server.
