Frequently asked questions

Questions about XML Formatter & Validator

Does this tool validate against an XSD schema?

No. This version checks whether the XML document is syntactically well formed, but it does not validate business rules or element structures against an XSD schema.

What is the difference between formatting and minifying XML?

Formatting adds indentation and line breaks to improve readability. Minifying removes unnecessary formatting whitespace to produce a more compact document.

Are XML comments preserved?

Yes. Comments are preserved unless a formatter configuration explicitly filters them out.

Is my XML uploaded?

No. Formatting, validation, file import and minification all run inside your browser.
