Frequently asked questions
Which SQL dialects are supported?
Common dialects such as MySQL and PostgreSQL among others; pick the right one so dialect-specific syntax is handled correctly.
Are keywords upper- or lowercase?
It is toggleable, e.g. SELECT vs select; choose a style and keep it consistent.
Are my queries sent to a server?
No, formatting runs locally in the browser; your queries do not leave the page.
Does formatting help with errors?
A clear structure makes typos, missing commas and wrong clause order easier to spot.
