FAQ
Which SQL dialects work?
Standard SQL dialects supported by sql-formatter (e.g. sql, mysql, postgresql, sqlite, bigquery). Pick a dialect if keywords differ.
Is my query sent to a server?
No. Formatting runs locally in your browser.
Does it validate SQL?
It formats; it does not execute or fully validate against a database engine.
Can I minify SQL?
Use Format with compact options off; for size reduction prefer removing comments manually or in your build.
