What is XAML Beautifier?

XAML Beautifier pretty-prints XAML markup — the XML-based UI description language used in WPF (Windows Presentation Foundation), UWP, .NET MAUI, Xamarin.Forms, and Avalonia. XAML is often auto-generated or copy-pasted in a single line, making it hard to read. This formatter normalises whitespace and indents each element so nested layouts like Grid, StackPanel, and DataTemplate hierarchies are clearly visible. It uses the same XML formatting engine as the XML Beautifier and supports all XAML namespace prefixes.

How to Use XAML Beautifier

1

Paste XAML source markup.

2

Choose indentation style.

3

Click Format.

4

Review the formatted XAML structure.

5

Copy or download the .xaml file.

Common Use Cases

  • Reading minified XAML exported from designer tools or code generators.
  • Formatting XAML snippets from Stack Overflow or documentation before using in a project.
  • Debugging layout issues in compressed XAML copied from build logs.
  • Preparing XAML examples for blog posts, documentation, or presentations.

Example Input and Output

A compact XAML layout is expanded with proper element indentation.

Compact XAML
<StackPanel><TextBlock Text="Hello" FontSize="20"/><Button Content="Click Me" Click="OnClick"/><TextBox x:Name="Input" Margin="4"/></StackPanel>
Beautified XAML
<StackPanel>
  <TextBlock Text="Hello" FontSize="20"/>
  <Button Content="Click Me" Click="OnClick"/>
  <TextBox x:Name="Input" Margin="4"/>
</StackPanel>

Privacy

XAML markup is formatted locally in the browser and is not uploaded.

Frequently Asked Questions

Does this validate XAML syntax?

No. It formats XML for readability only. Use Visual Studio or the XAML compiler to check for markup errors.

Does it support all XAML namespaces?

Yes. XAML namespace prefixes like x:, d:, mc:, and custom prefixes are treated as regular XML namespace attributes and preserved as-is.

Can it format MAUI and Avalonia XAML?

Yes. .NET MAUI and Avalonia use XML-based XAML dialects. The formatter handles them as generic XML, which covers all XAML variants.

Is my XAML uploaded anywhere?

No. Formatting runs entirely in your browser.
