XML Formatter

How to use XML Formatter

1. Open XML Formatter — 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 Formatter?

• 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 formatter tasks are one click away.

What people use XML Formatter for

• Making a machine-generated SOAP or API response readable.
• Inspecting a config, RSS or sitemap file that arrived as one long line.
• Locating the position of a parse error in a large document.

XML Formatter: limits and things worth knowing

• Whitespace between elements is generally insignificant, but whitespace inside mixed content — text and elements in the same parent — is part of the document. Reformatting mixed content can change meaning.
• CDATA sections are preserved untouched, which is what keeps embedded scripts and HTML intact.
• Malformed XML is reported with its parse error rather than being silently reformatted. Unlike HTML, XML has no error recovery: one unclosed tag makes the whole document invalid.

Is it private and secure?

Your privacy is built in. XML Formatter 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.
