XML Formatter

XML Formatter accepts raw XML text and returns a well-formed, human-readable version with consistent indentation. It ensures structural integrity while offering options to adjust indentation size and to minify output for compact payloads. The tool is designed for developers, API engineers, and data integrators who need predictable XML structure for logs, configurations, and data exchanges.
Conceptually, the process parses the input into a tree, then serializes it back with the chosen indentation, preserving CDATA sections, comments, and namespaces. If the input is not well-formed, the formatter reports the first error with location details to aid debugging. It does not fetch external resources unless explicitly provided, and it can operate on snippets or larger XML documents.
Use cases include preparing API payloads for documentation, cleaning up configuration files, and formatting data exports for QA reviews. The tool provides consistent indentation and optional minification to suit different development and deployment pipelines. Its value lies in reducing manual reformatting, improving diffs in code reviews, and ensuring uniform XML aesthetics across repositories.
The core differentiation is strict well-formedness validation combined with configurable formatting rules, preserving important XML constructs while delivering readable output suitable for both humans and machines.
