XML Formatter and Validator
Format XML, clean indentation, and check XML parse errors in your browser.
XML validation checks whether the document is well-formed. It does not validate an XSD, DTD, feed contract, or application-specific schema.
How to use XML Formatter and Validator
Best for
- Pretty-printing XML snippets, feeds, config files, and API samples.
- Checking whether pasted XML is well-formed before saving or sharing.
- Reviewing nested tags with readable indentation.
Steps
- Paste XML into the input box.
- Choose Format to indent the XML or Validate to check parse errors.
- Review any parse message before copying the formatted output.
Notes
- This checks whether XML is well-formed, not whether it matches a specific XSD or business schema.
- Large XML documents may be slow because formatting runs in the browser.
FAQ
Does XML Formatter upload my XML?
No. Formatting and parse checks run locally in your browser.
Does this validate against an XSD?
No. It checks basic XML parsing and formatting. Schema validation still needs a dedicated XML schema validator.
