How it works
Paste XML into the input field. The tool strictly checks XML syntax in your browser before formatting valid documents with the selected indentation.
Use cases
Format valid XML documents for review or get syntax feedback while developing.
Privacy
Your data is parsed securely in your browser memory and disappears when the page reloads.
Limitations
The tool validates XML syntax and formats valid documents; it does not validate XML schemas or DTDs. Extremely large files might be slow depending on your device.
XML Formatter FAQ
Can it format unformatted XML strings?
Yes. It parses the document tree and indents elements cleanly with 2 or 4 spaces.
Is the processed XML stored anywhere?
XML content remains in browser memory and is never saved to external storage.
What happens if the XML contains syntax errors?
The tool reports the parser's syntax error and leaves your source unchanged; parser details can vary by browser.
