XML Formatter
Runs entirely in your browser
Beautify and indent XML directly in your browser, based on element nesting.
What is XML Formatter?
XML Formatter re-indents an XML document so each nested element sits on its own line, making structure easy to scan. It's a text-based indenter, not a validator — it won't fix malformed XML, only make well-formed markup readable.
How to use XML Formatter
- Paste your XML into the Input box.
- Choose an indent size.
- Click Format, then copy the result.
Features
- Indents nested elements based on tag structure.
- Preserves CDATA sections and processing instructions exactly.
- Correctly handles self-closing elements.
- 100% client-side — your markup never leaves your browser.
Frequently Asked Questions
Is my XML uploaded to a server?
No. Formatting happens entirely in your browser.
Are CDATA sections and processing instructions preserved?
Yes. <![CDATA[ ... ]]> sections and <?xml ... ?> processing instructions are kept exactly as written, on their own line.
Does this validate my XML?
No. This is a text-based indenter, not a validator — it won't catch mismatched tags or invalid XML, only reformat well-formed markup.
Are attribute values changed?
No. Attributes stay exactly as written on the same line as their tag — only element nesting is indented.
