XML Formatter & Beautifier
Instantly transform messy, minified XML code into a perfectly indented, human-readable hierarchy. You can also reverse the process to minify your XML.
How to Use
- Paste your messy, unformatted, or minified XML string into the top Input panel.
- Select your preferred indentation style from the dropdown (the industry standard is 4 spaces).
- Click Format XML. The tool will parse your code and structure the nested nodes into a beautiful, readable hierarchy in the Output panel.
- If you are preparing XML data to be sent over an API or saved to a database and want to save space, click Minify XML to strip out all spaces and line breaks.
Features
Smart Hierarchy
Automatically tracks nested parent and child nodes to enforce perfect visual structure.
Instant Minification
Compress massive XML datasets into a single line of text to save bandwidth.
Zero Dependencies
Uses a highly optimized native Regex engine instead of bulky external libraries.
Privacy First
Your XML files (which often contain sensitive data) are processed entirely in your browser.
Why do we format XML?
XML (eXtensible Markup Language) is a structural language designed to store and transport data. Unlike HTML, which has predefined tags (like <p> and <h1>), XML allows developers to define their own tags (like <employee> and <salary>).
Because XML is frequently generated by automated server software, the output is almost always minified (meaning all the spaces, tabs, and line breaks have been removed to make the file size as small as possible). While minified XML is incredibly fast for computers to read over a network, it is practically impossible for a human developer to read or debug.
An XML Formatter solves this by reading the mathematical structure of the nodes and injecting proper spaces and line breaks, transforming an unreadable wall of text into a structured, hierarchical document.
The Data Parsing Suite
If you are working with JSON instead of XML, try our JSON Formatter or use the JSON Minifier to compress it. Need to convert a massive spreadsheet into a data payload? Use the CSV to JSON Converter. If you have a JSON payload but need YAML for a configuration file, instantly translate it using the JSON to YAML Converter.
Frequently Asked Questions
Does this tool validate my XML?
This tool is designed strictly as a beautifier and minifier. It relies on your XML being structurally valid (meaning every opening tag has a corresponding closing tag). If your XML is broken or missing tags, the formatting hierarchy will break.
Will formatting change my data?
No. Formatting only injects "whitespace" (spaces, tabs, and line breaks) between the structural XML tags. It will never modify the actual text or data values inside the tags.
Is the data sent to a server?
No. We respect your data privacy. The formatting algorithm runs exclusively inside your local web browser. Your XML is never transmitted over the internet.
Is it free?
Yes, 100% free with no limits.
