SQL Formatter — frequently asked questions
Does formatting change what my query does?
No. The formatter only adjusts whitespace, line breaks and keyword casing. The logic and results of your query stay exactly the same.
Which SQL dialects are supported?
It handles standard SQL along with common dialects, so queries written for popular databases are reformatted cleanly. Dialect-specific keywords are preserved.
Is my query data safe?
Yes. Everything runs client-side in your browser. Your SQL, including any table or column names, is never sent to or stored on a server.
