XML Formatter Online

Updated 2026-07-09

Beautify and pretty-print XML right in your browser. Paste raw or minified XML into the editor and SnapTools returns clean, properly indented output as you type — with basic syntax checking, configurable spacing, and one-click copy or download. Nothing is uploaded: all formatting happens locally, so it's safe for private feeds, configs, and API payloads.

A well-indented XML document is far easier to scan and debug than a single compressed line, and the inline checking catches unbalanced tags before they cause problems. Whether you're inspecting a SOAP response, a config file, or an RSS feed, the XML Formatter gives you readable structure in one step.

// how to use

  1. 1 Paste or type your XML into the input panel on the left — formatting starts as you type.
  2. 2 Open Settings to choose indentation (2, 4, or 8 spaces) for nested elements.
  3. 3 Read the clean, indented XML on the right; if a tag is unbalanced, the status bar flags it.
  4. 4 Click Copy or Download to take the result with you.

// faq

No. Formatting runs entirely in your browser, so your data never leaves your machine — safe for private feeds, configs, and SOAP payloads.
Yes. It does basic syntax checking and flags unclosed or mismatched tags in the status bar so you can find the problem quickly.
The XML Formatter expects every element to be properly closed and treats the document strictly, while the HTML Formatter understands void elements like br and img. Use the HTML Formatter for web markup.
Yes. Attributes, namespaces, and CDATA content are kept intact; only indentation and line breaks are added for readability.
The most common causes are a missing closing tag, mismatched element names, or an unescaped special character. The status bar points to the first issue it finds.
