SQL Formatter & Beautifier
Instantly format messy SQL into clean, readable, properly indented queries.
SQL Formatting Best Practices
- Uppercase keywords (SELECT, FROM, WHERE) — distinguishes SQL grammar from identifiers.
- Each clause on its own line — SELECT, FROM, WHERE, JOIN, GROUP BY, ORDER BY each start on a new line.
- Indent JOIN conditions — ON clauses should be indented under their JOIN for clarity.
- Use table aliases — short aliases (u for users) make complex queries much more readable.
- Comment complex logic — Use
-- commentto explain non-obvious filters or JOINs.
