Frequently Asked Questions

What SQL dialects are supported?
The formatter supports Standard SQL, MySQL, PostgreSQL, T-SQL (SQL Server), and PL/SQL (Oracle). Each dialect handles syntax nuances specific to that database engine, ensuring accurate formatting.
Can I control how SQL keywords are capitalized?
Yes. You can choose to format keywords as UPPER case, lower case, or preserve the original casing from your input. Upper case keywords are the most common convention for SQL readability.
Is my SQL data safe when using this formatter?
Absolutely. All formatting is performed locally in your browser using JavaScript. Your SQL queries never leave your machine and are never sent to any server.
