Paste XML, get consistently indented output instantly. Unlike a JSON formatter — where whitespace between tokens never means anything — an XML formatter has to be careful: only whitespace-only text between sibling elements is safe to throw away and re-indent.
Comments and CDATA sections are real content, not formatting noise, so this tool keeps both intact on every reformat. It also preserves whichever self-closing notation the original document used rather than rewriting it. Mixed content (text and elements interleaved in the same parent) is the one case where whitespace can become meaningful again — see the full guide below for that edge case.
Frequently asked questions
- Is this XML formatter free to use?
- Yes. It runs entirely in your browser — no signup, no data sent to a server.
- Will formatting delete my comments or CDATA sections?
- No. Comments and CDATA sections are preserved exactly as written — only whitespace-only text between sibling elements (pure indentation, not content) is re-indented.
- Does it rewrite self-closing tags like <empty/> into <empty></empty>, or the other way around?
- No. Both notations are semantically identical to any XML parser, so this tool preserves whichever one the original document used instead of normalizing it.
- Is my XML uploaded anywhere?
- No. Parsing and formatting happen locally in your browser tab — nothing is sent to a server.
