Frequently Asked Questions
Does this run or validate my SQL?
No — it only formats the text for readability. It does not connect to any database, execute the query, or check that it is semantically valid.
Is my query sent to a server?
No. Formatting happens entirely in your browser, so you can safely paste queries containing table or column names from private schemas.
Which SQL dialects are supported?
It formats standard SQL syntax used by MySQL, PostgreSQL, SQL Server, SQLite, and others. Very dialect-specific constructs are left intact but may not be re-indented.
