How to use
Parse XML with the browser's XML parser, report invalid markup, and produce indented or compact output for APIs and configuration files.
- Paste an XML document or response body.
- Choose formatted output or a compact version.
- Fix any parser errors, then copy the validated result.
Best for
- SOAP response inspection
- XML configuration cleanup
- Feed and sitemap debugging
Why the result matters
- Validation runs before formatting so malformed XML does not produce a misleading partial result.
- Formatting is intended for structural inspection and may normalize insignificant whitespace.
Example inputs
- Format a compact API response
- Validate nested tags
- Minify XML test data
FAQ
Does the tool validate XML syntax?
Yes. It uses the browser XML parser and reports parser errors before formatting.
Can I minify XML?
Yes. The minify action removes formatting whitespace between tags.
Will formatting preserve every whitespace character?
It preserves document content but may normalize whitespace that only separates tags.
Is the XML uploaded?
No. Parsing and formatting happen in your browser.
