XML Formatter
Beautify and indent XML documents for readability.
About XML Formatter
XML Formatter indents nested elements and validates that tags are balanced, which turns a single-line export into something a human can actually read.
It preserves CDATA sections and attributes, and reports the first mismatched tag instead of silently producing broken output.
How to use XML Formatter
- 1
Paste the XML
A document, a SOAP envelope, or an RSS feed.
- 2
Format
Choose indentation; attributes are kept on their element.
- 3
Validate the result
A mismatched closing tag is reported with its position.
Questions about XML Formatter
Does it resolve external entities?
No. External entity resolution is disabled, which prevents XXE-style attacks.
Will it change my data?
Only whitespace between elements. Text content and CDATA are left untouched.
Can it handle large files?
Documents of a few megabytes are fine; much larger ones are limited by browser memory.
Does it validate against a schema?
No, it checks well-formedness, not XSD conformance.
