SQL Prettifier

Format SQL queries into readable or compact output.

Last validated: 2026-02-14

SQL Prettifier reformats SQL queries into readable multi-line layout or compact single-line output for transport. It is useful during code reviews, incident debugging, and documentation updates where query clarity matters. The tool standardizes keyword casing and clause layout so complex statements become easier to scan quickly. Compact mode is useful when you need compressed SQL for logs or API payloads. Use it to reduce formatting noise, compare query revisions more easily, and improve maintainability in collaborative workflows.
