Complex subqueries, window functions, and multi-line comments.

Is this SQL Formatter safe for sensitive data & credentials?

Yes, 100%. All processing runs client-side in your local browser memory. No text, tokens, payloads, or logs are ever transmitted to any remote server or analytics engine.

Can I use SQL Formatter offline without internet?
