XML formatting for integrations
XML Formatter adds indentation around nested elements so API payloads, feeds, and configuration files become easier to inspect. It is especially useful when copied responses arrive as one long line.

Why use XML Formatter
- Beautify compact XML from API responses, SOAP messages, RSS feeds, or config files.
- Inspect parent and child nodes before writing XPath queries or parser rules.
- Prepare readable XML examples for bug reports, docs, and integration tickets.
- Compare formatted payloads when debugging partner data or feed changes.
About this tool
RSS, SOAP, and API payload review
Readable XML helps you check namespaces, repeated nodes, attributes, text content, and hierarchy before editing a parser or sending an integration issue to another team.
Formatting versus validation
Formatting is a readability step. If you need to prove the document is well-formed or matches an XSD, run XML validation after reviewing the formatted structure.
Example usage
Input
<user><name>Alex</name><role>Admin</role></user>
Output
<user>\n <name>Alex</name>\n <role>Admin</role>\n</user>
Practical guide for XML Formatter
Best practices
- Format XML before writing XPath rules or integration bug reports.
- Preserve source copies for signed XML, mixed content, and whitespace-sensitive data.
- Validate separately when syntax or schema correctness matters.
Common mistakes
- Assuming pretty XML is valid XML.
- Ignoring namespaces when inspecting formatted nodes.
- Changing whitespace inside text nodes that a downstream system treats as data.

FAQ
Does XML Formatter validate XML?
It is focused on readability. Use XML Validator when you need syntax validation, well-formedness checks, or schema-related review.
Can whitespace change XML meaning?
Yes, in some text nodes whitespace can matter. Be careful with mixed-content XML, preformatted text, and signed payloads.
What XML sources can I format?
Common sources include RSS feeds, SOAP responses, API payloads, sitemap files, SVG source, and configuration documents.
What should I check in formatted XML?
Check root elements, namespaces, repeated nodes, required attributes, encoded characters, and whether the hierarchy matches your parser expectations.
