About this tool
Uses the sql-formatterlibrary rather than a hand-rolled parser, since SQL dialects have enough syntax variation that a naive formatter would get many real queries subtly wrong.

FAQ
Does formatting SQL alter query logic or parameter bindings?
No. Formatting adjusts keyword casing and indentation whitespace while keeping query semantics identical.
Are comment lines preserved?
Yes. Single-line (-- comment) and block (/* comment */) SQL comments remain in place.
