About this XML formatter and beautifier

XML from an API, a log file or a message queue often arrives as one unreadable line. This free online XML formatter re-indents it into a clean, nested structure with consistent line breaks, so you can read, review and debug it. The document is parsed first, so an unclosed tag or stray character is reported with its exact line and column instead of being silently ignored, which also makes it a quick XML validator for well-formedness.

Everything runs in your browser and nothing is uploaded. Once it is formatted you can copy or download the result, open it as a collapsible tree in the XML viewer, convert it with XML to JSON, or transform it with the XSLT compiler.

Frequently Asked Questions

Everything you might want to know about the online XML Formatter.

An XML formatter adds consistent indentation and line breaks to make minified or poorly formatted XML easier to read without changing the underlying data.
No. Formatting happens entirely in your browser. Your XML is never uploaded, stored, or logged.
No, it formats well-formed XML only. If your XML has a syntax error — an unclosed tag, a stray character — the tool reports the line and column so you can fix it yourself.
Two spaces per nesting level, shown in the status bar as Indent: 2 spaces.
Yes. Use the Copy button to copy it to your clipboard, or Download to save it as a .xml file.
You can paste text or upload a file up to 10 MB.
Yes. The document is parsed before it's formatted, so any well-formedness error is caught and reported immediately rather than silently ignored. To explore a valid document's structure as a collapsible tree instead of indented text, try the XML Viewer.
Yes. Use the Wrap option to display long XML lines across multiple visual lines without changing the XML content.
The formatter only re-indents your XML for readability. The XSLT Compiler actually transforms XML using an XSLT stylesheet to produce a different document.
