Pretty-print XML in your browser with your chosen indentation. Entities stay decoded, attributes are kept, and broken markup is reported by the parser.
Paste XML, then format.
The formatted XML appears here.
Limit for uploaded files: 10 MB. Pasted text is not truncated by the tool — your browser’s memory is the ceiling.
Your file is never sent to a server. It is read and processed by your own browser, and the results are not stored.
XML from machines arrives as one line; XML from humans arrives with inconsistent indentation that makes nesting invisible. A formatter makes the tree readable, which is usually the fastest route to spotting a misplaced close tag.
Because the document is parsed and re-serialised, the output is guaranteed well-formed if it prints at all — a silent corrupter is worse than anything else.
This tool re-serialises structurally; the XML Validator tool answers whether the input is well-formed and where the first error is. Use the validator first when you suspect a broken file, then the formatter on the fixed input.
No. XML Formatter runs in your browser, and the file is read there rather than sent to a server for processing. Our host still sees ordinary page-request metadata, which is described on the privacy page.
Yes, XML Formatter is free, with no paid tier, no account, and no watermark added to your output. The limits are technical rather than commercial: file size, page count and supported formats are listed on this page.
XML Formatter supports .xml, .svg, .xaml, .xsd, .xsl, .txt files up to 10MB directly in your browser.
No. Elements, attributes and text content are re-emitted in the same order. Insignificant whitespace between tags may change because the output is re-indented.
Yes. Predefined and numeric character references are decoded and re-encoded consistently, so & stays & and will not break the re-parsed document.
They are never resolved. The tool reads structure only; a SYSTEM entity that would fetch a remote file is refused by design, so the tool cannot be used to probe internal services.
No. Formatting runs in this tab; nothing about the file leaves your device.
