How it works
- Paste your XML text into the editor.
- Choose your formatting options (indentation size or minify).
- The parser rebuilds clean hierarchical XML tags and flags any unclosed or invalid tags.
Privacy & Processing Information
Executed purely in your browser. XXE (XML External Entity) expansion is completely disabled for security.
No account, tracking, or file storage required.
Frequently Asked Questions
Is XML formatting safe against XXE attacks?
Yes. Our client-side parser parses the document strictly as a DOM string without resolving external entity references (XXE).
