Frequently asked questions
Which SQL dialects are supported?
Standard SQL, MySQL, PostgreSQL, MariaDB, SQLite, BigQuery, and Transact-SQL (SQL Server). Choosing the right dialect improves how keywords and syntax are formatted.
What does “keyword case” do?
Preserve keeps your keywords as-is, UPPER forces them uppercase (e.g. SELECT, FROM), and lower makes them lowercase. Only reserved keywords are affected — your table and column names are untouched.
Will it change my query’s meaning?
No. Formatting only adjusts whitespace, indentation, and keyword casing. The logic and results of your query stay exactly the same.
Is my SQL sent to a server?
No. Formatting runs entirely in your browser using JavaScript. Your queries never leave your device — safe for production and proprietary schemas.
