What is XAML Beautifier

Last reviewed: April 18, 2026

XAML (eXtensible Application Markup Language) is Microsoft's XML-based markup language for defining UI layouts in WPF, UWP, MAUI, and other XAML-based frameworks.

XAML Beautifier is an online tool that helps you format and beautify XAML.

It reformats XAML so the pasted content is easy to scan, diff, and share, no manual whitespace cleanup required.

Why use it

Make XAML easier to read, review, and debug.
Standardize XAML spacing and structure before sharing or committing output.
Clean up pasted XAML payloads from logs, APIs, or config files faster.
Avoid manual XAML formatting work when you need copy-ready output.

Example (before/after)

Before formatting

<Grid><Button Content="Save" Width="120" Margin="0,12,0,0" /></Grid>

After formatting

<Grid>
  <Button
    Content="Save"
    Width="120"
    Margin="0,12,0,0" />
</Grid>

Common errors

Invalid syntax

The tool cannot process input that already contains broken syntax or malformed structure.

Fix: Check the pasted content first and correct the syntax error closest to the reported failure point.

Incomplete pasted input

Partial snippets often fail when opening and closing characters are missing.

Fix: Paste the full block or file so the tool can evaluate the complete structure.

Wrong content type

Formatting or validating the wrong format produces misleading errors.

Fix: Make sure the content matches the tool you are using before processing it.
