XML Formatter & Beautifier
Paste XML or upload a file to add indentation, check XML syntax, and download the result. Formatting runs in your browser.
Quick start
- 1

- 4
Download the result
Download the current XML editor contents to your computer.
Data stays on your device
XML formatting runs locally in your browser. This tool does not upload your file for processing.
Format XML into readable nested elements and check for malformed syntax before processing it. Paste text or load a file, review the result, and download the editor contents. Syntax checking is separate from validating an application-specific XML schema.

Actions
XML Validation
Validates XML structure using the browser's DOMParser with detailed error messages for malformed input.
Privacy-Focused
Your XML data never leaves your device. All processing happens locally in your browser.
Multi-Format Support
Paste standard XML, well-formed XHTML, or SOAP XML. Upload accepts .xml and .txt files.
Readable XML
Indent nested elements to make XML easier to scan while retaining text and attribute values.
Is the XML formatter private?
Yes. All formatting happens entirely in your browser. Your XML data never leaves your device or touches our servers.
Does the formatter validate XML?
It checks whether XML is well-formed when you click Format or Compress and reports parsing errors. It does not check an XSD or DTD schema.
What XML formats are supported?
Paste well-formed XML, including XML-based SOAP messages or XHTML. The Upload button accepts .xml and .txt files.
Can I minify XML with this tool?
Compress serializes valid XML while preserving text and attribute values. Meaningful whitespace is retained, so output is not guaranteed to be one line or smaller.
Beautify XML and check its syntax
Paste a compact XML response, configuration file, RSS feed, or sitemap into the editor. Choose Format to make nested elements easier to read. The formatter checks whether the XML is well-formed before changing it; an error message helps you find problems such as an unclosed tag, mismatched element names, or an unescaped ampersand.
Compact input
<order id="42"><item>Notebook</item><quantity>2</quantity></order>After Format
<order id="42">
<item>Notebook</item>
<quantity>2</quantity>
</order>What does XML validation check here?
This tool checks XML syntax when you choose Format or Compress. For example, <item>Notebook</items> fails because the opening and closing tags do not match. Change the closing tag to </item> and format again. Literal ampersands in text must be escaped as &.
A well-formed document can still contain values or elements your application does not accept. This formatter does not validate against an XSD or DTD, so use your schema validator when you need to check required fields, data types, or allowed element order.
Preserve text, then download your XML
Formatting preserves text content and attributes. Mixed content, CDATA, and elements marked xml:space="preserve" are not reindented. Compress serializes the document without stripping meaningful text whitespace, so it may not produce a single line or a smaller file. Use Download to save the current editor contents as formatted.xml.
