Technical Specifications & How It Works
XML documents often become unreadable when generated without indentation by SOAP APIs, configuration tools, or sitemap generators.
This tool validates XML syntax using the browser's native DOMParser engine and indents nested elements with consistent two-space hierarchy.
Because processing executes client-side, proprietary configuration files and private API payloads remain strictly confidential.
Frequently Asked Questions
How are XML validation errors reported?
If the XML is malformed, the browser DOMParser pinpoints the error and displays a clear descriptive message.
Does minifying XML break CDATA or text nodes?
Minification strips extraneous inter-tag whitespace and comments without modifying the content inside element tags.
Is there any file size limit for XML formatting?
You can comfortably format XML files up to several megabytes directly in browser memory.
