Frequently Asked Questions

Is my database schema safe when formatting SQL online?

Absolutely. This SQL formatter runs entirely in your browser using client-side JavaScript. No query data, table names, or schema information is ever transmitted to a server.

What SQL dialects does this formatter support?

It supports standard ANSI SQL and is compatible with PostgreSQL, MySQL, SQLite, MariaDB, and most common SQL dialects. Keywords are automatically uppercased for readability.

Can I format SQL with subqueries and JOINs?

Yes. The formatter correctly handles nested subqueries, multiple JOIN clauses, CTEs (WITH statements), and complex WHERE conditions with proper indentation.

Does this SQL beautifier work offline?

Once the page loads, all formatting logic runs locally in memory. You can continue formatting SQL without an internet connection.

Is there a file size limit for SQL queries?

There's no hard limit. The tool processes queries in your browser's memory, so it can handle very large queries limited only by your device's available RAM.
