Angular Formatter
Format Angular HTML templates with consistent structure. It runs entirely on your device — nothing is uploaded.
Example
Format Angular HTML templates with consistent structure.
How it works
Prettier's Angular parser understands Angular template syntax and re-prints it cleanly.
Good to know
The Angular Formatter takes the HTML templates you write for Angular components and re-prints them with clean, consistent indentation, attribute wrapping, and spacing. It uses Prettier's Angular-aware parser, which means it recognizes Angular-specific syntax — interpolation like {{ value }}, property and event bindings such as [disabled] and (click), structural directives like *ngIf and *ngFor, and the newer @if/@for control-flow blocks — and won't mangle them the way a generic HTML beautifier might. It's aimed at Angular developers who want a quick, no-install way to tidy a template snippet without opening their editor.
Reach for it when you've pasted markup from a tutorial, merged a messy template, or inherited a component whose indentation drifted over time. It's also handy for normalizing a snippet before pasting it into a code review, a Git commit, or documentation, so reviewers see structure instead of formatting noise. Because it runs fully in the browser, you can use it on proprietary or client code without that code ever being uploaded.
To read the result, compare the output's nesting: each child element should sit one indentation level deeper than its parent, and long lists of attributes get wrapped one-per-line when they exceed the print width. The formatter changes only whitespace and line breaks — it does not rename bindings, reorder attributes by meaning, or alter the rendered output of your template, so a clean diff should contain layout changes only.
One caveat: this tool formats template (HTML) syntax, not TypeScript component logic or inline styles, so an inline template: string inside a .ts file may need to be extracted first, and a malformed template with an unclosed tag can cause a parse error rather than a fix. If you want the same rules applied automatically across a whole project, configure Prettier with the Angular parser in your build instead of formatting files one at a time here.
Frequently asked questions
Is my data uploaded anywhere?
No — everything runs in your browser. Your code never leaves your device, so it's safe for private work and runs offline once loaded.
Is this tool free?
Yes, completely free with no sign-up and no limits.
People also ask
Does the Angular Formatter work with the new @if and @for control flow syntax?
Yes. It uses Prettier's Angular parser, which understands the built-in control-flow blocks (@if, @for, @switch, @defer) introduced in modern Angular as well as the older structural directives like *ngIf and *ngFor.
Will formatting my template change how the component renders?
No. The formatter only adjusts whitespace, indentation, and line wrapping. It does not change element order, binding values, or attribute meaning, so the rendered output stays the same.
Can it format an inline template inside a TypeScript component file?
This tool formats standalone Angular HTML template markup. For an inline template defined as a string inside a .ts file, you would typically extract the template HTML first, or use Prettier directly in your project where it can handle embedded templates.
What's the difference between an Angular formatter and a plain HTML beautifier?
A plain HTML beautifier may not recognize Angular-specific syntax such as bindings, interpolation, or structural directives and can break or misindent them. The Angular parser is aware of these constructs and prints them correctly.
Does it fix errors in my Angular template?
No. It re-prints valid templates cleanly but does not correct logic or fix broken markup. An unclosed tag or invalid syntax will usually produce a parse error instead of formatted output.
Can I control the indentation width or other formatting options?
This tool applies Prettier's standard defaults for Angular templates. To customize options like print width, tab width, or quotes, run Prettier locally with a configuration file in your project.
Is the Angular Formatter the same as running Prettier locally?
It uses the same Prettier engine and Angular parser, so the output matches Prettier's defaults. Running Prettier locally adds the ability to use a config file, format many files at once, and integrate with your editor or build.
