Frequently asked questions

Which SQL dialects are supported?

The formatter handles standard SQL syntax used by MySQL, PostgreSQL, SQL Server, and SQLite. Vendor-specific syntax (e.g. T-SQL or PL/pgSQL blocks) is preserved but not deeply re-indented.

Will this change my query's behavior?

No. Formatting only adjusts whitespace and keyword casing - it never changes operators, identifiers, or query semantics.

Can I format very long queries?

Yes. There's no length limit - formatting runs in your browser, so even multi-thousand-line queries work.
