XML Formatter

เกี่ยวกับ XML Formatter

The XML Formatter is a free, browser-based tool for beautifying, minifying, and validating XML documents. XML is used everywhere — REST API responses, SOAP web services, configuration files, RSS/Atom feeds, SVG graphics, Android layouts, Maven POM files, and countless data exchange formats. When XML arrives as a compact single-line string or is poorly indented, understanding its structure is time-consuming and error-prone. The beautifier parses the tag hierarchy and adds consistent indentation so that every parent-child relationship is immediately visible. Prolog declarations (<?xml version="1.0"?>), self-closing tags, and XML comments are all handled correctly without disrupting the indent level. The built-in validator uses the browser's native DOMParser to check for well-formedness errors such as unclosed tags, mismatched element names, illegal characters, and missing attribute quotes — displaying the exact error message so you can fix it quickly. The minifier strips all inter-element whitespace to produce the most compact representation. Everything runs in your browser, so your XML data — which may include API keys in attributes, private records, or internal configuration — is never sent anywhere.
