Comprehensive Guide & Technical Mechanics

About XML Formatter — Free Online Tool

XML Formatter indents an XML document, and refuses to touch one that is not well-formed.

The document is checked before it is reformatted, and a mismatched closing tag, an unquoted attribute value, an unterminated comment or more than one top-level element stops the job with the line and column of the fault — you get the location, not a half-indented file. Only once that check passes is the document re-indented at the width you chose. Whitespace between elements is normalised as part of that, so mixed content, where text and child elements share a parent, is reflowed; the output is for reading rather than for byte-for-byte comparison.

Both the well-formedness check and the indentation run in your browser; the document is not uploaded.

Reading a SOAP response captured from a log, inspecting an RSS feed or a sitemap, tidying a configuration file before editing it, and locating the tag that breaks a feed reader.
