About the XML Formatter
Minified XML is painful to read: a whole sitemap on one line, with nesting you can only guess at. This formatter rebuilds the layout with clean, consistent indentation, preserving attributes, comments, CDATA blocks, and processing instructions.
It doubles as a lightweight validator, flagging mismatched or unclosed tags with specific errors. One click minifies the document back down when readability isn't the goal.
Where it helps most
Making inherited XML reviewable.
Inspecting SOAP responses
Inspecting a SOAP response shows what the service actually returned. The formatted view makes the document reviewable rather than merely present.
Fixing dead RSS feeds
Checking an RSS feed that stopped updating reveals the malformed entry that broke it. One unclosed tag can silence a whole feed.
Reviewing sitemaps
Reviewing a sitemap before submitting it to search engines catches structural mistakes early, when they are still cheap to fix.
Editing build files
Editing a pom.xml or AndroidManifest.xml is safer with clean indentation revealing the true nesting, since one misplaced tag breaks the whole build.
Validation included
Strict rules, clear explanations.
Well-formedness checks
XML has strict rules: every opened tag must close, attribute values must be quoted, and the document needs exactly one root element. Violations are flagged with an explanation.
Catches cryptic failures
The unclosed tag or stray ampersand that would make a parser reject the document gets caught before it reaches a failing system.
No sides taken
JSON won the API wars for new development, but XML remains entrenched where schemas, namespaces, and document validation matter. Formatting takes no sides.
XML Formatter: built for trust
Paste, format, copy. Validation rides along, free, with no signup.
XML Formatter FAQs
The common violations are unclosed or mismatched tags, unquoted attribute values, more than one root element, and unescaped special characters like a raw ampersand. The formatter flags these with an explanation instead of guessing, since strict parsers reject the whole document over any of them.
