Frequently asked questions

Does this tool validate my XML?

It indents your XML and runs a rough tag-balance check, but it is not a full validating parser. It will not catch wrong attribute order or DTD issues.

Is my XML uploaded anywhere?

No. Formatting and minifying run entirely in your browser.

Which XML features are supported?

Elements, attributes, comments, CDATA sections, processing instructions like the XML declaration, and self-closing tags.

Can I also compress XML?

Yes, the Minify button collapses whitespace between tags so you can paste compact XML into configs.
