XML이란?
XML (eXtensible Markup Language) is a text-based format for storing and transporting structured data. Unlike HTML which focuses on displaying data, XML focuses on what the data is. It uses custom tags to describe data hierarchically, making it human-readable and machine-parseable.
XML is widely used in web APIs, configuration files, RSS feeds, SOAP web services, SVG graphics, and data interchange between systems. It provides a standardized way to structure information so different applications can understand and process it.

자주 묻는 질문
Beautify (or pretty-print) adds proper indentation, line breaks, and spacing to make XML readable and easy to navigate. Minify removes all unnecessary whitespace, reducing file size by 10-30%. Use beautify for development and debugging; use minify for production and data transmission.
Our validator checks for well-formedness: balanced opening/closing tags, proper attribute syntax, valid characters, and correct nesting. It identifies missing closing tags, unclosed attributes, and invalid XML declarations. Note: This validator checks well-formedness only, not structural validity against DTD or XSD schemas.
Yes, this formatter supports files up to 10MB. Processing happens entirely in your browser, so no data is sent to servers. Very large files may temporarily slow your browser. For files over 10MB, consider splitting them or using command-line tools like xmllint or xmlstarlet.
Completely secure. All processing happens in your browser using JavaScript — your XML never leaves your computer. No data is stored, logged, or sent to our servers. You can use this tool offline, and it works even without an internet connection after the page loads.
The tree view shows your XML structure hierarchically, making it easy to understand nesting and relationships. Each node displays the tag name, number of attributes, and child count. Click expand/collapse buttons to drill down into complex XML documents, or use the Expand/Collapse All buttons to navigate quickly.
You can choose from 2 spaces, 4 spaces, 8 spaces, or tab indentation. Select your preference before clicking Beautify. Different teams have different standards — 2 spaces is compact, 4 spaces is standard, and tabs allow each developer to customize display width in their editor.
