Styled XML keeps working
Pages that use an XSL stylesheet (XSLT 1.0), like WordPress sitemaps or device status pages, display again after Chrome removes XSLT. Web apps that call XSLTProcessor keep working too, on the sites you choose.

All four images are screenshots of sample files in Chromium 156 with XSLT turned off, as in Chrome from 17 November 2026: first without XMLNest, then with XMLNest 1.4.
One XML viewer, several ways to read a file
Open an XML address. XMLNest shows it as a styled page, in a reader view, as a tree or as formatted source.
Feeds and sitemaps you can read
RSS and Atom feeds open in a reader view with a built-in podcast player. Sitemaps become a table you can filter, sort and export to CSV or JSON. Find sitemap errors and load child sitemaps in one click.
A clear XML tree
Fold and unfold, search names and values, copy a node, its value or its path. A broken file shows the line and column of the error.
Free online XML tools
Need a quick check without installing anything? These six tools by the XMLNest team run in your browser: your XML is never uploaded.
XML Formatter
Format, beautify or minify XML. Clear error messages with the exact line.
XML Validator
Check that XML is well-formed. The first error comes with its line, its column and a suggested fix.
Sitemap Checker
Check an XML sitemap for errors: URLs, dates, duplicates and limits, each with its line. Sort and export the URLs.
XML to JSON Converter
Convert XML to JSON and choose how attributes and repeated elements are written.
XSLT Tester
Test an XSLT 1.0 stylesheet on your XML and see the rendered result and its source.
XPath Tester
Test an XPath expression on your XML and see every matching node, with its path and line.

Pick the one that fits. Each one links to a short guide.

No. XMLNest is independent and not affiliated with Google. It uses the open-source xslt-polyfill library.
Why does Chrome ask me to allow access to sites?
