Which SQL dialects are supported?

The formatter handles standard SQL syntax and works well with MySQL, PostgreSQL, SQLite, and SQL Server. Dialect-specific functions are preserved as-is.

Does it validate my SQL?

No — the formatter only beautifies the structure. It does not check for syntax errors or validate against a database schema.

Are keywords uppercased automatically?

Yes. All standard SQL keywords (SELECT, FROM, WHERE, JOIN, GROUP BY, etc.) are automatically uppercased during formatting.

Is my query sent to a server?

No. Formatting is done entirely in your browser with JavaScript. Your SQL never leaves your device.
