XML Formatter

About XML Formatter

XML beautifier reformats minified or poorly indented XML into a clean, readable structure with proper nesting. Paste your XML and this free, browser-based tool processes it instantly without uploading anything to a server. No account needed, making it safe for use with internal data exports, SOAP payloads, or proprietary config files.

The XML Formatter takes raw, unformatted, or minified XML and outputs properly indented, human-readable XML with consistent structure. XML is used in many contexts where formatted output matters for readability: configuration files (Maven POM files, Android manifests, Spring configuration), data exchange formats (RSS feeds, SOAP API responses, SVG files, Microsoft Office XML), and document formats (DOCX, XLSX, ODT internally). When XML is minified or poorly indented, it becomes extremely difficult to read, debug, or review in a code review. This formatter applies configurable indentation (2 spaces, 4 spaces, or tabs) and preserves all content including CDATA sections, processing instructions, and XML declarations. The tool validates the XML structure as it formats and reports any parse errors with the line and character position. It runs entirely in your browser and your data never leaves your device.

XML remains widely used in enterprise software, document formats, and legacy integrations despite JSON becoming the dominant format for new APIs. Many developers encounter raw or minified XML when debugging SOAP web services, inspecting Office Open XML files (docx or xlsx renamed to zip), reading RSS or Atom feeds, or working with Android resource files. The formatter handles all standard XML constructs: element attributes, CDATA sections (content treated as literal text rather than markup), processing instructions (like the XML stylesheet declaration), and namespace prefixes. One common source of confusion is preserving whitespace in text nodes: the formatter keeps intentional whitespace inside text content while normalizing structural whitespace between elements. For XML with very deep nesting (like complex XSLT or XSD schemas), the indented output makes the hierarchy much clearer. If you are debugging a SOAP request or response, paste the raw envelope and the structure of the body, headers, and fault elements becomes immediately readable. The validator catches common XML errors: unclosed tags, mismatched tag names, invalid characters in attribute values, duplicate attribute names, and missing namespace declarations.

How to use XML Formatter

  1. Paste your XML code into the input area
  2. Choose indent size and click format, minify, or validate
  3. Copy the formatted output or stats to your clipboard

Frequently Asked Questions

What does an XML formatter do?
An XML formatter takes raw, unstructured, or minified XML code and reformats it with consistent indentation and line breaks making it human-readable and much easier to navigate, debug, and understand.
Is my XML data safe when using this tool?
Yes. The XML Formatter processes everything entirely in your browser no data is sent to any server. Your XML content stays completely private and secure on your local machine.
What's the difference between XML formatting and XML validation?
Formatting only adjusts the visual structure of your XML indentation and spacing without checking if the content is correct. Validation checks whether the XML follows proper syntax rules and conforms to a defined schema like DTD or XSD.
