XML Formatter is a free browser-based tool for formatting, validating, minifying, and viewing XML. Paste your XML code into the editor or import an .xml or .txt file, then format it into a clean and readable structure.
The tool can work as an xml validator online when you need to check XML syntax before using the document. Use xml pretty print to add indentation and make nested elements easier to read, or use the xml minifier to remove unnecessary whitespace when you need a more compact version.
The built-in xml viewer provides a collapsible Tree view, making it easier to browse large XML documents and understand their element hierarchy. You can also sort attributes, strip comments, make empty elements self-closing, or inline text depending on how you want the output formatted.
For developers working with APIs, SOAP envelopes, WSDL files, feeds, and configuration documents, the formatter provides a quick way to clean and inspect XML directly in the browser.
Step 1: Add Your XML
Paste XML into the editor, load the sample, or import an .xml or .txt file.
Step 2: Choose Formatting Options
Select Beautify or Minify and choose your preferred indentation. You can also enable Sort Attributes, Strip Comments, Self-Closing Empty, or Inline Text.
Step 3: Format and Inspect
Click Format to create readable XML or Minify to make it more compact. Open Tree view to browse nested elements and attributes.
Step 4: Copy or Download
Copy the formatted XML or download the result when you need a separate file.
.xml and .txt file importPretty Print XML
Use xml pretty print to turn compressed or difficult-to-read XML into a properly indented structure for development and debugging.
Validate XML Online
The xml validator online functionality helps identify XML syntax problems before you use the document in an application or API.
Minify XML
Use the xml minifier to remove unnecessary whitespace when you need a smaller XML payload.
View Large XML Documents
The xml viewer Tree view lets you expand and collapse elements instead of scrolling through a large block of markup.
Work With SOAP and WSDL
Format SOAP envelopes, WSDL documents, API responses, feeds, and configuration files to make their structure easier to inspect.
Prepare XML for Sharing
Clean comments, normalize attributes, and format the document before copying it into documentation, tickets, or development discussions.
