Frequently asked questions
Is my SQL query sent to a server?+
No — formatting happens entirely in your browser using the sql-formatter library. Your queries never leave your device.
Which SQL dialects are supported?+
Standard SQL, MySQL, PostgreSQL, BigQuery, DB2, Hive, MariaDB, PL/SQL, SQLite, and TransactSQL.
Does it validate my SQL?+
No — it formats and highlights structure only. Validation against a live database is not performed.
Can I format very large queries?+
Yes — the formatter runs client-side and handles large queries well. For extremely long scripts consider splitting them.
