XML Formatter
Paste messy XML and get clean, indented output — or minify it to a single line, with validity checked as you go.
How to use the XML Formatter
- Paste your XML into the left box.
- Click “Beautify” for readable indentation, or “Minify” to compress it.
- Copy the result — any XML errors are flagged below.
About the XML Formatter
This XML formatter takes tangled, single-line or badly-indented XML and lays it out cleanly, with each element nested under its parent so you can actually read the structure. When you need the opposite — the smallest possible payload for transport or storage — the Minify button strips every gap between tags and collapses it to one line. As you work, the tool parses your XML and flags any errors, so you catch an unclosed tag or a stray character before it breaks something downstream.
XML still underpins a huge amount of the web — RSS feeds, SVG, sitemaps, SOAP APIs, Office documents, Android layouts and countless config files. Being able to quickly pretty-print a response or shrink a document is a small thing that saves real time when you are debugging.
It all runs locally in your browser, so your data is never uploaded. Need the data in a different shape? Convert it with XML to JSON, then tidy that with the JSON formatter or inspect it in the JSON viewer.
Frequently asked questions
Does it validate my XML?
It checks that the XML is well-formed — properly nested and closed — and shows an error if it is not. It does not validate against a specific schema or DTD.
Will formatting change my data?
No. Beautify only adds whitespace between elements and Minify only removes it; the actual content and structure stay identical.
Is my XML sent to a server?
No. Parsing and formatting happen entirely in your browser, so nothing leaves your device.
