XML Formatter/Validator

Format, minify, validate, and visualize XML documents as a tree.

Input

Validation uses the browser's XML parser, which reports well-formedness errors (mismatched tags, bad attributes, encoding issues). XSD schema validation is not performed. XML→JSON maps attributes to @keys, repeated elements to arrays, and infers numbers and booleans.

Frequently Asked Questions

>Is XSD schema validation supported??
No, the tool checks well-formedness (matching tags, valid structure) using the browser XML parser. XSD validation is not performed.
>Why is my XML reported as invalid??
XML is strict: mismatched tags, unescaped &, duplicate attributes, or invalid entity references all fail parsing. The error message points to the first problem found.
