What this developer tool does

This formatter normalizes indentation, whitespace, braces, Angular templates, decorator metadata, and selected configuration files without adding external libraries.

Detect code type → protect strings and comments → normalize indentation → preserve Angular bindings and control flow → calculate changed lines and processing time.

Complex template literals and computed decorator metadata are preserved conservatively and may require manual review.

Example

A compact Angular component is expanded into readable TypeScript with normalized braces, template indentation, and consistent spacing.

Tips for better output

Use Auto Detect for mixed Angular snippets.
Review inline templates containing complex expressions.
Use the same indentation settings as your project.
Run the Angular Validator after formatting.
