XML Formatter

Pretty-print, compact, and validate XML quickly.

Last validated: 2026-02-14

XML Formatter formats XML for readability, minifies it for transport, and checks structural validity. It is useful when debugging SOAP/XML APIs, config files, and feeds where indentation and nesting are hard to read in raw form. By switching modes, you can inspect a clean pretty-printed version or generate compact output for storage/transmission. Invalid structure errors are surfaced quickly so malformed payloads are easier to diagnose.
