XML Formatter & Validator

About the XML Formatter & Validator

XML Formatter & Validator pretty-prints any XML document with consistent indentation, minifies it to a single line, and validates structure using the browser's built-in DOMParser — the same engine Chrome and Firefox use for XHTML, SVG and RSS feeds.

How to use

1. Paste your XML into the input area.
2. Pick an indent size (2 spaces, 4 spaces or tab).
3. Click Format, Minify or Validate — the output appears below and the status row reports the first parse error if any.

Benefits & key features

• Spot unclosed tags, bad attributes and stray characters instantly.
• Works on SVG, RSS / Atom feeds, sitemaps, SOAP envelopes and config files.
• Minify mode strips whitespace without breaking CDATA blocks.
• Validation is powered by the same parser your browser uses — results match production behaviour.

Pro tip

If your XML has a fixed schema, validate it here first and then paste the formatted version into an XSD-aware IDE for the final structural check against your XSD.

Why choose toolsfy for Text & Document tools?

Writing tools on the web typically lean toward either "blog-post-assistant with an AI upsell" or "plain counter with zero insight". toolsfy aims for the middle ground: a collection of sharp, single-purpose text utilities that run inline while you draft, with no usage cap and no sign-up. Because every tool is client-side, you can happily paste confidential paragraphs, leaked transcripts or half-finished blog drafts without second-guessing where they end up.

Common use cases

• Students counting words against strict assignment limits while the essay is still being edited, not after it has been submitted.
• Copywriters A/B-testing two versions of a landing page paragraph and checking whether one reads at a different grade level than the other.
• Journalists cleaning up a pasted transcript — removing line breaks, converting case, stripping extra whitespace — before a Ctrl-F search.
