What this tool does

XML formatting adds consistent indentation and line breaks at element boundaries, making deeply nested structures easy to read. Minification does the opposite — stripping whitespace for compact storage or transmission.

Why use XML Formatter online?

XML Formatter in the browser saves context switching: no CLI install, no fragile one-liners, and instant feedback for teammates who do not live in the terminal. It is ideal for debugging, demos, and quick checks during code review.

Frequently Asked Questions

Does this validate my XML?
Yes. The tool uses the browser's native DOMParser to detect and report any well-formedness errors before formatting.
What XML standards are supported?
Any well-formed XML 1.0 document — including SVG, XHTML, RSS, Atom, SOAP envelopes, and custom data formats.
Is this tool free to use?
Yes. All Skybin developer tools are free with no account, API key, or usage limits.
Does my data get sent to a server?
No. Processing runs in your browser whenever possible. Sensitive input never leaves your device unless a tool explicitly fetches a URL you provide (e.g. OG Validator).
Can I use this on mobile?
Yes. The tools work in modern mobile browsers, though a desktop screen is easier for large JSON or PDF workflows.
How is this different from desktop apps?
There is nothing to install or update. Open a bookmarked URL and start working — ideal for quick tasks during development or support calls.
Are there keyboard shortcuts?
Most tools support standard paste (Ctrl+V / Cmd+V) and select-all in text areas. Copy buttons provide one-click output.
Does Skybin store my history?
No. We do not log tool inputs or outputs. Refreshing the page clears in-memory state unless the tool encodes state in the URL.
