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.

Frequently Asked Questions

What does "this XML file does not appear to have any style information associated with it" mean?

It is not an error. The browser is telling you the XML document has no XSLT stylesheet attached, so it shows the raw document tree instead of a rendered page. Sitemaps, RSS feeds and API responses are meant to look like this. To read the file comfortably, paste it into an XML formatter for indentation and syntax highlighting.

What is an XML file?

XML (eXtensible Markup Language) is a text format that stores structured data in nested tags, like HTML but with custom tag names. It is used for configuration files (pom.xml, AndroidManifest.xml), data exchange (SOAP APIs, RSS feeds), documents and SVG graphics. Any text editor can open it, and a formatter makes it readable.

How do I validate an XML file?

Paste it into this tool: it checks that the XML is well formed, meaning every tag is closed, properly nested and correctly quoted, and points to the exact line of the first problem. Well formedness is what breaks parsers in practice; validation against a specific schema (XSD or DTD) is a separate step that requires the schema file.

What is the difference between XML and JSON?

Both store structured data as text. XML uses nested tags with attributes and supports comments, namespaces and schemas, which made it the standard for enterprise systems, SOAP and configuration files. JSON is lighter, maps directly to objects in most languages, and dominates modern web APIs. This tool converts XML to JSON when you need to move data between the two worlds.
