XML Formatter

XML arrives from APIs and exports as one enormous line, and reading it is impossible until it has been indented. This free xml formatter online fixes that, and does it without changing anything except whitespace.\n\nThat distinction matters more than it sounds. Many formatters parse XML into an object tree and serialise it back out, which silently drops comments, mangles CDATA sections, discards processing instructions and reorders attributes. This one walks the document as tokens and re-indents in place, so what comes out is byte-identical apart from the whitespace you asked to change.\n\nShort elements are collapsed onto a single line, so a name element containing a few words does not sprawl across three. Indentation is configurable to two spaces, four, or tabs to match whatever your project uses, and a minify mode strips inter-tag whitespace when you need the smallest possible payload.\n\nMalformed input is rejected rather than silently mangled, with the browser's own parser diagnosis included where available — usually pointing straight at the unclosed tag. Everything runs locally. Pair it with the XML to JSON Converter when you need to work with the data rather than read it, or the Sitemap Generator if the XML in question is a sitemap.
