Client-side only — your XML is never sent to a server.

Use this free online XML formatter to beautify, validate, and minify XML documents directly in your browser. Paste any XML string and get instant syntax error detection, clean indented output, and a compact minified version for production use.
This tool supports standard XML including namespaces, CDATA sections, processing instructions, and comments. All processing is done client-side — your data is never uploaded to a server.
Select the indentation style and paste your XML to instantly see properly structured, indented output with colour-coded syntax. Validation errors are shown immediately so you can locate and fix malformed tags, unclosed elements, or bad attribute syntax without running a separate parser.
Use the minify option to strip all whitespace for embedding in JSON payloads, HTTP requests, or configuration strings where line breaks are not permitted.
Is my XML data sent anywhere?
No. Parsing and formatting run entirely in your browser using the native DOMParser. Your data never leaves your device.
What is the difference between XML and JSON?
XML is tag-based and supports attributes, namespaces, and mixed content. JSON is lighter and better for most modern APIs. Use the JSON to XML or XML to JSON converters to switch between formats.
Can it format HTML?
Only if the HTML is valid XHTML or well-formed XML. Standard HTML5 with optional closing tags or boolean attributes will fail XML validation.
