XML Formatter & Minifier
About XML Formatter & Minifier
Beautify messy or minified XML with correct indentation, or minify XML for production by stripping whitespace. The formatter validates syntax as it works and highlights the exact location of any malformed tags, unclosed elements, or encoding errors, which makes it invaluable for debugging feeds, configs, SVGs, and API responses. It handles deeply nested structures and large documents, and everything runs locally in your browser.
How To Use
- Paste your XML into the input, or load an XML file from your device.
- Choose to format (beautify with indentation) or minify (strip whitespace).
- Review any syntax errors flagged with their location, then copy the cleaned XML.
Example
Input: A minified or poorly indented XML config or RSS feed.
Output: The same XML, neatly indented and validated, with any syntax errors highlighted.
Who Uses XML Formatter & Minifier
- Developers who prefer private, browser-only tools for formatting, validation, and data work.
- Engineers who need fast local tools without installing anything or uploading code.
- Teams that want private — files and text stay on your device and are never uploaded to a server.
Frequently Asked Questions
Does it validate XML?
Yes. While formatting, the tool checks tag matching, nesting, and attribute syntax, and reports the line and position of any error it finds.
Can it handle large XML files?
Yes. Formatting and validation run in your browser, so the tool handles large configs, feeds, and API responses without a server round-trip.
What is the difference between format and minify?
Formatting adds indentation and line breaks for readability. Minifying removes them to reduce file size for production transfer. Use format while editing and minify for shipping.
Is my XML uploaded anywhere?
No. Everything runs locally in your browser, so confidential configs and unpublished feeds never leave your device.
