What SQL dialects does this formatter support?

This formatter supports standard SQL syntax that works with MySQL, PostgreSQL, SQLite, SQL Server, Oracle, and most other SQL databases. It formats all common keywords and clauses.

Is my SQL query sent to a server?

No! The formatting happens entirely in your browser using JavaScript. No data is transmitted to any server, so your queries remain completely private.

Can I customize the indentation?

Yes, you can adjust the indent size from 2 to 8 spaces using the slider. This lets you match your team's code style preferences.

Does the formatter change my query logic?

No, the formatter only changes whitespace and capitalization. It never modifies the logic or structure of your SQL query.
