Frequently Asked Questions
What SQL statements does this formatter support? +
The formatter handles all major SQL statement types including SELECT, INSERT, UPDATE, DELETE, CREATE TABLE, and ALTER TABLE. It properly formats JOINs, WHERE clauses, GROUP BY, HAVING, ORDER BY, UNION, and subqueries.
Does the formatter change my SQL logic? +
No. The formatter only changes whitespace and letter casing of SQL keywords. It never modifies your table names, column names, values, or query logic. Your formatted SQL is functionally identical to the original.
Can I customize the formatting options? +
Yes. You can toggle uppercase keywords on or off and adjust the indentation size (2 or 4 spaces). These options let you match your team's SQL style guide.
Is my SQL query sent to a server? +
No. All formatting happens entirely in your browser. Your SQL queries are never transmitted, logged, or stored anywhere. This makes it safe to format queries containing sensitive data.
Why should I format my SQL queries? +
Formatted SQL is easier to read, debug, and review. Consistent formatting helps teams collaborate, makes complex queries understandable at a glance, and reduces errors during code reviews.
