About This Tool

This free online XML Formatter and Validator helps you clean and verify XML payloads quickly for integrations, feeds, and legacy data pipelines. Use format mode to improve readability with indentation and line breaks. Use validate mode to detect parser issues before passing XML into downstream APIs or ETL flows.

When you need compact output for transport or snapshots, minify mode removes unnecessary whitespace while preserving structure. This is useful for QA, migration scripts, and troubleshooting malformed responses. The tool runs in-browser for fast iteration and copy-ready output during development.
