よくある質問

Which SQL dialects are supported?

Standard ANSI plus dialect-specific keywords from MySQL, PostgreSQL, SQL Server, SQLite, and BigQuery. Rare vendor extensions may not indent perfectly.

Does it validate my SQL?

No. It only reformats - a syntax error in your SQL will still appear in the output. Use your database's EXPLAIN for validation.

Are comments preserved?

Yes. Both -- line comments and /* block comments */ are kept in place.

Is my query uploaded?

No. Formatting runs entirely in your browser.
