Frequently asked questions

Which SQL dialects are supported by the formatter?

Standard ANSI SQL, PostgreSQL, MySQL, MariaDB, SQLite, Microsoft SQL Server (T-SQL), and Oracle PL/SQL syntax are all cleanly formatted.

Can the tool capitalize all SQL reserved keywords automatically?

Yes! The uppercase keyword feature standardizes commands like SELECT, FROM, WHERE, INNER JOIN, and ORDER BY while preserving original case on table and column names.

Is my database query structure kept private?

Yes. Formatting runs locally using in-browser tokenizers. No query schemas, table structures, or proprietary SQL logic are ever sent over the network.
