XML Formatter
Format and beautify XML with proper indentation.
This XML Formatter parses XML and re-indents it for readability, directly in your browser. It validates the document while formatting, so a malformed or mismatched tag surfaces as a clear error with its line and column when the parser can pinpoint one. Copy or download the formatted result — your XML is never uploaded.
How to use
- 1Paste XML into the input, or upload an .xml file — nothing leaves your browser.
- 2Click Format to validate and indent it.
- 3Copy or download the result.
Frequently asked questions
What is an XML formatter for?
It re-indents an XML document — nesting child elements under their parents with consistent indentation — so a document that arrived as one long line or with inconsistent spacing becomes easy to read.
When is this useful?
Inspecting an API's raw XML response, cleaning up a config file (like a pom.xml or web.config), or reviewing an XML export from another system before editing it.
Does formatting also validate the XML?
Yes — since formatting requires actually parsing the document, a malformed or mismatched tag is caught and reported (with line/column when the parser can determine one) rather than silently producing garbage output.
Is my XML sent to a server?
No. Formatting happens entirely in your browser — your data never leaves your device.
