XML Formatter
Pretty-print XML
What is XML Formatter?
Pretty-print or minify XML with full validation. The live validator reports parse errors with specific messages, so malformed tags or mismatched quotes are easy to fix. Useful for reading dense XML API responses, inspecting config files, or preparing XML for diffing and documentation.
How do I use XML Formatter?
- Paste XML into the input panel.
- Choose Pretty or Minify mode and set indent size.
- Copy or download the output.
When should I use XML Formatter?
XML Formatter handles display-layer cleanup. To convert XML into JSON for programmatic use, use XML to JSON. To turn XML into tabular CSV, use XML to CSV.
Can it format one-line XML?
Yes — the pretty-printer indents every element and attribute onto its own line. Nested children are wrapped at the chosen indent width (2 or 4 spaces).
Does it validate against a schema?
No — it only checks well-formedness (balanced tags, escaped entities, valid characters). For XSD validation, use a server-side validator.
How does it handle CDATA and comments?
Both are preserved exactly. CDATA sections stay as <![CDATA[...]]>; comments keep their text and whitespace.
Is my file uploaded anywhere?
No. Everything runs in your browser. Your files never leave your device, and there is no server component for this tool.
