Paste into SQL Formatter, tweak options, and copy the output. Formatting and conversion run in the browser for this tool.
Tips for better results
Keep a backup of original input before bulk transforms. Invalid input should show an error instead of silent corruption.
Privacy and offline-friendly processing
Whenever possible, SQL Formatter processes your data locally with JavaScript in this page. That means drafts, secrets, and unfinished work stay on your device by default. Prefer this workflow when you do not want to upload sensitive text, tokens, passwords, or files to a third-party service.
