Frequently asked questions

Which SQL dialects are supported?

Standard SQL, MySQL, PostgreSQL, SQLite, MariaDB, BigQuery, SQL Server (T-SQL) and Oracle (PL/SQL).

Does formatting change what my query does?

No — it only reformats whitespace, indentation and keyword case; the SQL logic is unchanged.

Can I uppercase the SQL keywords?

Yes — choose UPPERCASE, lowercase or preserve for keyword casing.

Is my SQL executed or uploaded?

Neither — it's only beautified locally in your browser, so nothing is run or sent to a server.

Can I set the indentation?

Yes — pick 2 spaces, 4 spaces or tabs.
