What Is an XML Formatter?
An XML Formatter (also known as an XML Beautifier or Pretty Printer) is a tool that takes raw, minified, or poorly formatted XML and organizes it with proper indentation, line breaks, and spacing. This makes the structure much easier to read, inspect, and debug.
Our XML Formatter also performs basic syntax validation, helping you catch errors like unclosed tags, missing attributes, or incorrect nesting.
How to Format XML Online
To format XML online, simply paste your XML document into the editor and click Format XML. The tool will automatically add proper indentation and line breaks to make the structure clear.
You can also use the validator to check for syntax errors and ensure your XML is well-formed.
XML Formatter for API & SOAP Responses
API responses and SOAP messages often return XML in a single line, making them difficult to inspect. Our XML Formatter converts these responses into readable, well-structured documents.
This is essential for developers debugging web services, inspecting SOAP envelopes, and analyzing API payloads.
XML Formatter for Configuration & Sitemap Files
Configuration files, RSS feeds, and sitemap files are often stored as XML. Our tool helps you inspect and debug these files by formatting them clearly.
Whether you're working with application configs, sitemap.xml files, or RSS feeds, our formatter makes them easy to read and verify.
Validate XML Syntax
Our XML Formatter includes basic validation to catch syntax errors like unclosed tags, incorrectly nested elements, and malformed attributes. This helps you produce well-formed XML that works reliably in your applications.
For complete validation against a specific schema (XSD), use a dedicated XML validator tool.
Is XML Formatter Private?
Yes. All XML formatting and validation happens locally in your browser. Your XML documents are never uploaded to a server.
This makes our XML Formatter ideal for inspecting sensitive API responses, configuration files, and development data.

Is my XML uploaded to a server?+
No. XML formatting is performed in your browser, so your XML does not need to be uploaded to a remote server for formatting.
Is this XML Formatter private?+
The formatter processes XML locally in the browser, which means the XML content does not need to leave your device for formatting.
Can I copy the formatted XML?+
Yes. After formatting, you can copy the cleaned XML and use it in your code, API testing, configuration files, or development workflow.
Why is my XML not formatting correctly?+
Invalid XML syntax such as unclosed tags, incorrectly nested elements, or malformed attributes can prevent proper formatting. Check the reported error and correct the XML before formatting it again.
Does formatting XML change its data?+
Formatting normally changes whitespace and indentation to improve readability while preserving the XML elements and their values.
Can developers use this XML Formatter for debugging?+
Yes. Developers can use it to inspect API responses, SOAP messages, configuration files, RSS feeds, sitemap files, and other XML documents during development and debugging.
Does XML formatting make the file smaller?+
No. Pretty printing generally adds whitespace and indentation for readability. If you need a smaller XML document, use an XML minifier instead.
