XML Formatter FAQ
Can I validate XML here?
Yes. The tool checks XML syntax as you edit and reports invalid documents with an error message and location when available.
Does minifying XML change its data?
Minifying removes unnecessary formatting whitespace. Review XML that intentionally depends on text whitespace before using a minified result.
Is my XML sent to a server?
No. Formatting, validation, and minification run locally in your browser. DevKit does not upload or store your XML.
Can I use XML from APIs or configuration files?
Yes. It is useful for API payloads, application configuration, sitemaps, RSS feeds, and other XML documents.
