How does this online SQL query formatter help with query optimization and debugging?

Formatting long, messy SQL queries makes join conditions, filters, and nested subqueries immediately visible, allowing developers to spot missing indexes, cartesian joins, or syntax mistakes in seconds.

Can I format SQL queries generated by ORMs like Prisma, Hibernate, or Entity Framework?

Yes! Simply copy the raw SQL query log output from your application console, paste it here, and format it to easily inspect generated ORM queries.
