XML

A free online XML formatter and beautifier that pretty-prints, indents, and minifies XML markup entirely in your browser. Paste a dense or machine-generated document and it re-indents every nested element into a clean, readable tree, or strips insignificant whitespace to compact the markup for storage or transmission. Because all processing runs client-side, your XML is never uploaded to a server — making it safe for configuration files, SOAP payloads, and other sensitive markup. It is well suited to reformatting API responses, tidying exported data, and inspecting the structure of documents that arrive as a single unbroken line.

Common uses

• Beautify a minified or single-line XML response so its structure is readable while debugging.
• Pretty-print a dense SOAP envelope or RSS/Atom feed to inspect the element hierarchy.
• Minify an XML document to shrink it before storing it or sending it over the wire.
• Reformat machine-generated XML that has no line breaks into a properly indented tree.
• Tidy an exported configuration or data file so nested elements are easy to scan.
• Normalize inconsistent indentation across an XML file before committing it to version control.

Frequently asked questions

What is the difference between formatting (beautifying) and minifying XML?

Beautifying adds line breaks and indentation so nested elements are easy to read; minifying removes insignificant whitespace to produce the most compact valid markup. Both keep the document semantically identical — only the whitespace between elements changes.

Does formatting change the meaning of my XML?

No. Formatting only adds or removes insignificant whitespace between elements; element names, attributes, namespaces, and text content are all preserved exactly.

Is my XML uploaded to a server?

No. Formatting and minifying run entirely in your browser, so your markup never leaves your device. This makes it safe to paste configuration files and other sensitive documents.

What indentation does the XML formatter use?

The formatter indents each nested level for readability. Minifying instead removes the whitespace between elements to produce the smallest valid output.

Can it reformat XML that is all on one line?

Yes. Single-line or machine-generated XML with no line breaks is re-indented into a readable, hierarchical structure.

What happens if my XML is not well-formed?

Well-formed markup formats cleanly. If the document has structural problems such as an unclosed tag or a mismatched element, formatting cannot reliably reindent it until the markup is corrected.
