Why Format SQL?
Minified or hand-written SQL queries quickly become impossible to read — especially when they contain nested subqueries, multiple JOINs, or long WHERE clauses. The SQL Formatter adds consistent indentation, capitalises reserved words and breaks each clause onto its own line so the logic is immediately clear.
SQL Keyword Reference
| Clause | Purpose |
|---|---|
| SELECT | Choose columns to return |
| FROM / JOIN | Specify source tables |
| WHERE | Filter rows |
| GROUP BY | Aggregate rows |
| HAVING | Filter aggregated results |
| ORDER BY | Sort output |
| LIMIT / OFFSET | Paginate results |
Tips
Consistent SQL formatting helps code reviewers spot logic errors faster. It is also useful before pasting queries into documentation, Slack or README files. All processing happens in your browser — no query is ever sent to a server.
