No installations, no backend requests, no data tracking—just fast, secure, and reliable XML formatting right from your browser. Optimize your productivity with a clean UI, blazing performance, and robust XML parsing capabilities—built to handle even the heaviest datasets with ease.
Key capabilities
- Smart formatting: Applies hierarchical indentation, keeps attributes aligned, and restructures compact XML for human-friendly review.
- Lossless minify: Remove whitespace and line breaks for production payloads without touching data.
- Streaming uploads: Drag and drop `.xml` files up to 30MB+ and process them entirely in-browser.
- History & downloads: Save formatted snippets locally, rename them, and re-download in one click.
Privacy & reliability
Just like the JSON formatter, the XML experience is completely local—no uploads, no external APIs, no telemetry. Your XML never leaves your machine, making it safe for confidential configs, large API responses, or log exports.
Robust validation highlights malformed markup using friendly error cards so you can resolve issues before shipping data down-stream.
