About XML Formatter

XML Formatter is a tool for beautifying and formatting XML data into a readable, properly indented structure. Designed for developers and engineers who need to quickly organize XML from API responses, configuration files, or data exports. Supports three indent styles — 2 spaces, 4 spaces, and tabs — and a minify mode that strips unnecessary whitespace between tags to reduce file size.

Correctly preserves XML comments () and CDATA sections (<![CDATA[...]]>), and automatically converts special characters (&, <, >) to XML entities (&, <, >) for syntax compliance. Detects XML syntax errors (unclosed tags, mismatched tags, multiple root elements, unclosed CDATA sections) in real-time and displays detailed error messages to pinpoint issues.

When XML includes API credentials, personal information, or other sensitive data, review the input before sharing or saving the formatted result. Seeing validation feedback and formatted output side by side makes it easier to prepare XML for code review or documentation.

How to use XML Formatter

Paste your XML into the input area on the left. You can copy from a file or type directly.
Select your preferred indent style (2 spaces, 4 spaces, or tab) or minify mode using the buttons above the output.
The formatted XML appears in real-time on the right. Click the Copy button to copy to clipboard.
If there are syntax errors, a red indicator and detailed error message will appear in the status bar.
