Instant Structural Formatting

Developers lose hours staring at broken DOM node nesting. Utilize our local browser engine to reconstruct minified scripts without uploading proprietary UI logic to arbitrary servers.

Automated Indentation

Our DOM parser calculates exact mathematical node depth, actively repairing missing brackets or entirely broken indent cascades across thousands of lines.

Dual Support Engine

Seamlessly toggle between complex HTML nesting logic and cascading CSS style rule structures without needing two separate online utilities.

Zero Network Risk

Have sensitive class names or proprietary application architecture? Process it here safely. The formatting libraries run 100% locally in your active Javascript scope.

Frequently Asked Questions

Does this formatter support embedded CSS within HTML tags?

Yes, our syntax parser intelligently detects <style> and <script> tags natively embedded within an HTML document and correctly cascades their internal indentations down to the root scope.
