How to Use
 
 
  1. Paste or type your XML in the input area.

  3. Adjust the indent size (2 or 4 spaces).
  4. Copy the output with the copy button.
 
XML Formatting
 
 
XML formatting adds consistent indentation and line breaks to make XML documents readable. This is purely a display transformation — the XML content and structure remain identical. Formatted XML is easier to read and debug, while minified XML reduces file size for transmission.
 
Features
 
 
  • Validates XML structure before formatting.
  • Configurable indent size (2 or 4 spaces).
  • Handles processing instructions, comments, self-closing tags, and text nodes.
  • Minify mode removes all unnecessary whitespace.
 
Use Cases
 
 
  • API debugging: Format XML responses from SOAP, REST, or GraphQL APIs to quickly inspect the data structure.
  • Configuration files: Prettify application config files (web.xml, pom.xml, .csproj) for easier editing and review.
  • SOAP and RSS: Make SOAP envelopes and RSS/Atom feeds readable for troubleshooting and validation.
  • Data exchange: Format XML exports from databases, spreadsheets, or enterprise systems before importing them elsewhere.
  • Documentation: Present well-formatted XML examples in technical documentation or tutorials.
 
Tips
 
 
  • Use 2-space indentation for compact output or 4-space for maximum readability.
  • Minify XML before transmitting it over the network to reduce payload size.
  • If the formatter reports a parsing error, check for unclosed tags, mismatched quotes, or invalid characters.
  • XML is case-sensitive — <Tag> and <tag> are different elements. Formatting does not change case.
  • For very large XML files, consider using a streaming parser instead of loading the entire document into memory.
 
Privacy
 
 
All formatting happens in your browser using the built-in DOMParser. No data is sent to any server.
