XML Formatter

The XML Formatter tool provides a deterministic, high-fidelity method to convert irregular XML into clean, readable markup. It accepts a raw XML string, preserves semantic content, and outputs indentation-consistent XML suitable for reviews, diffs, and integration into development pipelines.

Conceptually, the tool parses input with a standards-compliant XML parser, then re-serializes the document with user-selected indentation (2 or 4 spaces) and optional modes such as pretty print or minification. It preserves comments, CDATA sections, and processing instructions, ensuring the resulting output remains faithful to the original data.

Who benefits: software developers, testers, data engineers, and system integrators who frequently exchange XML payloads. Unique value comes from no external dependencies, fast processing, and the ability to validate and normalize structure in a single pass, reducing review time and diffs.

Core features include formatting with consistent indentation, optional minification, preservation of non-element content, and optional syntax validation. Typical use cases include preparing API payloads, formatting configuration files, transforming logs for readability, and creating reproducible samples for documentation.
