XML Viewer

How to use XML Viewer

1. Open XML Viewer — it runs entirely in your browser with no setup.
2. Paste or type your input into the text area, or upload a file where supported.
3. Set any options you need. The result appears in the output panel — there is no upload step and no waiting on a server.
4. Review the output instantly; large inputs are handled locally without lag.
5. Copy the result to your clipboard or download it. Your data never leaves the page.

Why use XML Viewer?

• 100% free with no limits, no sign-up and no watermarks.
• Private by design — your data are processed in your browser and never uploaded to a server.
• Fast and lightweight, with instant results even on a phone or a slow connection.
• Works everywhere — any modern browser on Windows, macOS, Linux, Android or iOS.
• Part of a full developer tools suite, so related xml viewer tasks are one click away.

What people use XML Viewer for

• Exploring a large XML feed, config or SOAP response as a navigable tree.
• Checking the nesting of an unfamiliar document before writing an XPath.
• Confirming that a generated sitemap or feed has the structure you expect.

XML Viewer: limits and things worth knowing

• Attributes are shown alongside their element rather than as children, which is the distinction most XML-to-JSON conversions lose.
• A parse error is reported with its line and column instead of a partial tree — XML has no error recovery, so a document either parses or does not.
• Namespace prefixes are shown as written. Two documents can be semantically identical while using different prefixes for the same namespace URI.

Is it private and secure?

Your privacy is built in. XML Viewer runs completely on your device, so whatever you enter stays in your browser and is never transmitted, logged or stored on any server.

Network activity: none. Nothing is sent and nothing is fetched. This tool makes no network request at all once the page has loaded — which is why it keeps working if your connection drops.

You do not have to take that on trust — our privacy proof page publishes the Content-Security-Policy that enforces it, lists every third party it permits, and shows how to verify the whole claim yourself.
