Frequently asked questions

Is my SQL sent to a server?

No. Formatting happens 100% in your browser. Your query never leaves your device, ideal for SQL with sensitive data.

Which dialects are supported?

Standard SQL, MySQL, PostgreSQL, SQLite, Transact-SQL (SQL Server) and BigQuery, each with its syntax particularities.

Does it change my query?

No. It only reorganizes the formatting (spaces, line breaks, uppercase keywords). The query logic is exactly the same.

Does it work for minified one-line SQL?

Yes. It takes any query, whether on one line or unordered, and makes it readable with the correct structure.
