XML Formatter & Beautifier
Validate, beautify, and minify your XML code with precision. Free online tool for developers.
Mastering XML Structure and Formatting
XML (Extensible Markup Language) is the backbone of data interchange for countless legacy systems, configuration files (like sitemaps and RSS feeds), and SOAP APIs. However, unlike JSON, XML can become notoriously difficult to read when generated by machines without proper line breaks or indentation. This XML Formatter is designed to transform messy, minified, or unreadable XML strings into a structured, human-readable hierarchy.
Why Use an XML Beautifier?
Debugging configuration errors or API responses is nearly impossible when the entire payload is a single line of text. Beautification adds intelligent whitespace and indentation to visualize the parent-child relationships between tags.
1. Error Detection: Our tool attempts to parse the XML before formatting. If your code has unclosed tags or invalid syntax, the formatter will alert you, acting as a quick validator.
2. Standardization: When working in teams, maintaining a consistent coding style is crucial. By enforcing a specific indentation (e.g., 4 spaces), you ensure that diffs in version control systems (like Git) show actual content changes rather than just formatting noise.
Minification: Optimization for Production
While humans need whitespace to read code, computers consider it wasted bandwidth. "Minification" is the process of stripping all unnecessary characters—spaces, newlines, and comments—from the source code. This reduces file size and improves parsing speed for the receiving application. Use the Minify button above to prepare your XML payloads for transmission or storage, potentially saving kilobytes of data per request in high-volume systems.
Safe Client-Side Processing
Security is paramount when handling sensitive data like API keys or personal information often found in XML. Unlike many server-side tools, this formatter runs 100% in your browser using JavaScript. Your data never leaves your device, ensuring complete privacy and zero latency. Whether you are a system admin checking a `config.xml` or a developer integrating a legacy API, you can paste with confidence.
