Free online XML tools
Small tools for the XML you handle every day, from API responses to feeds and sitemaps. Each one runs entirely in your browser: your files are never uploaded and you need no account.
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.
XPath Tester
Test an XPath expression on your XML and see every matching node, with its path and line.
Kobunsho Viewer
Open the official documents (kobunsho) sent by e-Gov and the Japan Pension Service straight from their ZIP, then print them or save them as PDF.
Italian E-Invoice Viewer
Open an Italian e-invoice, XML or signed P7M, and read it as a clean invoice. Print it or save it as PDF; attached PDF files open too.
Why are these tools free?
They are made by the team behind XMLNest, a free Chrome extension for reading XML, available on the Chrome Web Store. They cost nothing, need no account and have no daily limit. Your XML stays in your browser, is never sent to xmlnest.com or to anyone else and is gone when you close the tab.
