XML Formatter

Indent Spaces
Formatted Output 
 
 
How to Use
 
 
  1. Paste or type your XML in the input area.
  2. Click Format to prettify with indentation, or Minify to compress.
  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.
 
FAQ
 
 
What's the difference between Format and Minify?
 
Format adds indentation and line breaks to make the XML readable, while Minify strips all unnecessary whitespace to shrink the file size. Both only change appearance — the XML's content and structure stay identical.
Is it safe to paste business XML?
 
Yes. Formatting and validation are both done with the browser's built-in DOMParser, and the XML you enter is never sent to or stored on a server. You can safely work with internal config files or confidential data.
Is there a limit on the size of XML I can format?
 
There is no fixed size limit in the tool, but because it loads the entire document into memory, very large files may slow down depending on your device's performance.
Are comments, processing instructions, and self-closing tags preserved?
 
Yes. The tool handles processing instructions, comments, self-closing tags, and text nodes, and none of them are lost when formatting or minifying.
What should I check if formatting reports an error?
 
The tool validates XML structure before formatting. If it reports a parsing error, check for unclosed tags, mismatched quotes, or invalid characters. Remember that XML is case-sensitive, so <Tag> and <tag> are different elements.
