Private by design. Every tool runs 100% in your browser — your code, text, and tokens never leave your device. Nothing is uploaded or stored.

Frequently Asked Questions
Why does my XML refuse to format?
Usually unescaped & or < inside text, or mismatched tags. The formatter surfaces the error location so you can escape or repair it.
Does indentation change XML parsing?
Only inside mixed-content text nodes. Element-only XML is unaffected; the formatter preserves significant whitespace.
Is my XML validated?
It is formatted, not schema-validated. Well-formedness errors are caught; semantic validation still needs an XSD.
