XML Formatter

Free XML Formatter and Beautifier Online

An XML formatter takes raw or minified XML and restructures it with proper indentation and line breaks, making nested structures readable at a glance. XML is used in SOAP APIs, RSS/Atom feeds, Android layouts, Maven and Gradle config files, SVG graphics, and cross-platform data exchange. Minified or machine-generated XML is nearly impossible to read without reformatting.

This free online XML formatter also validates structure, converts XML to JSON, and lets you run XPath queries, all without uploading any file to a server.

How to format XML online

1. Paste your XML into the input area (or import a file).
2. Click Format to beautify and validate the structure instantly.
3. Use the XML to JSON tab to convert the document to JSON format.
4. Enter an XPath expression to query and extract specific nodes.
5. Copy the formatted output or download the result.

Beautify vs Minify XML

• Beautify: Adds indentation and line breaks for readability. Use when debugging API responses, reading config files, or reviewing data.
• Minify: Strips all whitespace and optional formatting to reduce file size. Use before embedding XML in production builds or transmitting over the network.

Common XML use cases

• SOAP APIs: Format verbose SOAP request and response bodies for debugging.
• RSS and Atom feeds: Read and inspect podcast or blog feed XML.
• Android development: Pretty-print layout XML and AndroidManifest.xml files.
• Maven / Gradle: Tidy up pom.xml and build configuration files.
• SVG: Format SVG markup exported from design tools.
• Data migration: Convert XML data exports to JSON for use in JavaScript applications.

XPath tester

XPath (XML Path Language) lets you navigate and query XML documents using path expressions. This tool includes an integrated XPath tester: paste your XML, enter an XPath expression like //item/title, and see all matching nodes highlighted instantly. Useful for scraping, testing XSLT transforms, or extracting values from API responses.

"This XML file does not appear to have any style information associated with it"

If your browser shows this message, nothing is broken. It simply means the XML document has no XSLT stylesheet attached, so the browser displays the raw document tree instead of a rendered page. This is completely normal for sitemaps, RSS feeds and API responses: they are made for machines, not for display. To actually read the file, copy the XML and paste it into this formatter: you get indentation, syntax highlighting and a collapsible structure. You only need to care about the message if you expected the XML to render as a styled page, in which case the document is missing its <?xml-stylesheet?> declaration.
