XML Formatter
Paste XML text, then format, minify, or validate it instantly — free, private, and processed entirely in your browser.
About the XML Formatter
Minified or poorly-indented XML is hard to read and easy to make mistakes editing. This tool formats XML with proper indentation, checks it's valid, and can minify it back down when you need a compact version instead.
Invalid XML shows a clear error rather than a broken result. Everything runs locally in your browser using native browser XML parsing.

Paste your XML
Paste XML text, or upload an .xml file.
Step 2
Format or minify
Choose to pretty-print with indentation, or minify to a single compact line.
Step 3
Copy the result
Copy your formatted or minified XML.
Frequently Asked Questions
How do I know if my XML is valid?
If your XML has a syntax error, you'll see a clear error message pointing to the problem, rather than a silently broken result.
What's the difference between formatting and minifying?
Formatting adds indentation to make XML easy to read; minifying strips unnecessary whitespace to make the file as small as possible.
Can I convert XML to JSON?
Not currently — this tool focuses on formatting, validating, and minifying XML itself.
Is my data uploaded anywhere?
No. Parsing and formatting happen entirely in your browser.
