XML Formatter
Format and pretty-print XML.
About the XML Formatter
XML appears in sitemaps, legacy APIs, RSS/Atom feeds, and enterprise exports. Formatting indented XML makes structure obvious and helps you catch mismatched tags before a parser rejects the file.
How to use
- Paste your XML.
- Format / pretty-print it.
- Fix any structural issues the output exposes.
- Keep a minified or compact version only if your pipeline requires it.
Common XML issues
- Mismatched or unclosed tags
- Invalid characters in unexpected places
- Encoding declaration mismatches
- Namespaces that look “wrong” until you inspect prefixes carefully
Tips
- For sitemaps, validate URL loc values and lastmod dates after formatting.
- Do not confuse HTML with XML — void elements and omitted tags differ.
FAQ
Is indented XML different data? No. Whitespace between elements is usually insignificant for data XML (except in mixed content designs).
