FAQ
Why should I format SQL queries?
Formatted SQL is dramatically easier to read, review, and debug. It makes JOIN conditions, WHERE clauses, and subqueries immediately visible — especially important in team code reviews.
Does formatting change the query logic?
No — formatting only changes whitespace and capitalization. The query executes identically before and after formatting.
What SQL dialects are supported?
The formatter handles standard SQL keywords that work across MySQL, PostgreSQL, SQL Server, and SQLite. Dialect-specific functions are preserved as-is.
