About this tool: XML Formatter & Validator
Parse XML with the browser DOM parser, report friendly syntax errors, pretty-print or minify the document and copy the resulting XML.
It is intended for development and data-cleanup workflows, with errors kept inside the interface so malformed input does not crash the page.
XML Formatter & Validator is presented in the shared NexterHub tool layout so the working controls stay near the top while the method, example, limitations and related utilities remain available below the result.
How it works
DOMParser parses the input with the application/xml MIME type. A parsererror node is treated as invalid XML; valid documents are serialized back to text and optionally pretty-printed.
Practical example
Input <root><item>NexterHub</item></root> can be formatted onto readable indented lines and copied.
Important notes
Validate the output in the context where you will use it, especially when the source data is incomplete or uses an unsupported syntax variant.
Privacy & processing
The primary formatting, parsing, encoding or conversion logic for this tool runs in the browser in the current build.
