SQL Formatter
Make a query easier to review while preserving strings and comments in supported dialects.
How this tool works
A dedicated SQL formatter handles token spacing and clause layout more reliably than regular-expression replacements. Choose generic SQL, PostgreSQL, MySQL, or SQLite syntax.
Formatting is not syntax validation and cannot guarantee meaning for every vendor extension. No query is sent to a database.
Examples
- Format a join with a WHERE clause.
- Keep a comment near its query.
- Check keywords inside string literals remain text.
Common use cases
Worked synthetic example
Valid example
select id from orders where id=7
Expected: SELECT id / FROM orders / WHERE id = 7. Line breaks and casing help review clauses; the query is not executed.
Failure or warning to recognize
Warning / interpretation
Formatting a vendor-specific extension and assuming it was validated.
Expected: A vendor extension may still receive formatted output; that output does not certify SQL syntax or query meaning.
