What SQLFormat.org is

SQLFormat.org is a free online tool for formatting SQL statements, available in a browser and through an API. The browser formatter processes statements locally using Pyodide and sqlparse. Users can adjust keyword and identifier case, indentation, output format, comment removal, and compact mode. Its API formats SQL or splits a string into separate statements and returns JSON results, with a limit of 500 requests per hour for a single IP. The privacy policy says browser-handled SQL is not sent to servers or third parties, stored on the server, or logged. It also says IP addresses are logged for security and performance monitoring and that errors go to Sentry. The linked sqlparse Python module can be used in other applications and is released under the New BSD License. Its parser does not validate SQL and is dialect-agnostic, so it can parse syntactically incorrect statements; the site names no specific dialects. Users can report bugs or send feedback through the page’s Feedback button.
