ABOUT THIS TOOL

XML Formatter — Beautify & Validate XML Online

Validate and pretty-print XML with configurable indentation using the browser XML parser.

Formatting starts with XML validation

Toolmera parses the input as application/xml before formatting it. Malformed tags, broken nesting and other well-formedness errors are reported instead of silently producing misleading output.

After validation, the browser serializes the document and Toolmera adds readable indentation.

Serialization can normalize the document

XML serializers can normalize quoting, namespace output and some whitespace details even when the logical document structure is unchanged.

Review formatted output carefully before replacing whitespace-sensitive XML, digital signatures or documents where byte-for-byte identity matters.
