XML Formatter
Pretty-print, minify, and validate XML in the browser. Configurable indent, live syntax check, stats, import and download.
Uses the browser DOMParser. Namespaces, attributes, and self-closing tags are preserved. Minify removes whitespace between tags.
How it works
Paste or import XML
Paste XML text or import a .xml file up to 5 MB. Invalid syntax is flagged live under the input label.
Format or minify
Format adds indentation (2 or 4 spaces). Minify removes extra whitespace. Validate confirms the document parses without producing output.
Copy or download
Copy the result or download formatted.xml. Stats show element count, attributes, depth, and size savings after minify.
Why format XML?
Minified XML from APIs and logs is hard to read. Pretty-printing reveals structure for debugging RSS feeds, SOAP payloads, SVG markup, and config files.

Questions
What does XML Formatter do?
It pretty-prints or minifies XML using the browser DOMParser and XMLSerializer — no server upload.
Will formatting change my data?
Only whitespace between tags changes. Element names, attributes, text content, and structure stay the same.
Does it support namespaces?
Standard XML with namespaces parses and formats. Exotic documents may need a dedicated XML tool.
What is the difference between Format and Minify?
Format adds readable indentation. Minify removes all unnecessary whitespace to reduce file size.
Is my XML sent to a server?
No. Processing runs entirely in this tab.
Is there a daily limit?
No. This tool has no daily cap.
