ToolsSoup's XML Formatter is a free online tool that formats, beautifies, and minifies XML right in your browser. Paste messy or minified XML and get clean, properly indented output in one click, or compress it back down to a single line. Invalid XML is caught instantly — no uploads, no sign-up, and nothing leaves your device.

      

        
What is an XML formatter?

        
An XML formatter — also called an XML beautifier or pretty printer — rewrites raw XML with consistent indentation and line breaks so it is easy to read. It also checks that your XML is well-formed, so mismatched or unclosed tags are reported right away. Developers use it to inspect API responses, configuration files, SOAP messages, RSS feeds, and SVG.

        
      

      

        
How to format XML online

        
Formatting XML with ToolsSoup takes just a few seconds:

        
  1. Paste your XML into the input box on the left.
  2. Click Format to indent it, or Minify to compress it onto a single line.
  3. Copy the result, or fix any error shown below the editor.

      

      

        
What is the difference between formatting and minifying XML?

        
Formatting adds indentation and line breaks to make XML readable, while minifying removes the whitespace between tags to make the file as small as possible. Both keep your data identical — the elements, attributes, and text are unchanged — so you can switch back and forth freely.

Frequently asked questions

        

          
Is this XML formatter free?

          
Yes. Every tool on ToolsSoup is completely free to use, with no account, sign-up, or hidden limits.

        

        

          
Is my XML data safe?

          
Absolutely. All formatting happens locally in your browser using JavaScript, so your XML is never sent to or stored on any server.

        

        

          
Why am I getting an 'Invalid XML' error?

          
The formatter requires well-formed XML. Common causes are unclosed tags, mismatched opening and closing tags, missing quotes around attribute values, or stray special characters. Fix the issue and try again.

        

        

          
What is the difference between formatting and minifying?

          
Formatting indents the XML for readability, while minifying strips the whitespace between tags to shrink the file. Neither changes your actual data.

        

        

          
Does it work with SVG and SOAP?

          
Yes. SVG and SOAP are XML, so any well-formed document of either kind formats and minifies just like other XML.
