The Format function adds uniform indentation to XML for improved readability. Minify removes whitespace between tags to produce a smaller file size. Validate identifies structural issues, such as unclosed or mismatched tags, and reports each error by its specific line number. Simply paste your XML into the editor, run an operation, and then download or copy the output.

Paste your XML into the input editor and click Format. The tool rewrites the markup using consistent indentation and line breaks that correspond to the nesting depth of the elements. Tag names, attributes, and text content are preserved without changes.
Click Minify to remove the whitespace between tags, creating a compact, single-line document. This process reduces the file size to allow for faster transfers across a network. Text content located inside elements is not affected.
The validator checks XML for well-formedness by looking for unclosed tags, mismatched opening and closing pairs, missing version attributes in the declaration, and other structural issues detected by the browser's parser. Each detected problem is listed with its line number and a brief explanation.
A well-formed document adheres to basic XML syntax rules: every opening tag has a matching closing tag, attributes are quoted, and there is exactly one root element. A valid document goes a step further by conforming to a specific schema (such as a DTD or XSD). This tool checks for well-formedness; it does not validate against external schemas.
Yes. After you have formatted or minified the code, click Download to save the result as an .xml file, or click Copy Result to place it on your clipboard.
No. The formatting, minifying, and validation processes are all executed via JavaScript directly in your browser. The XML you paste into the tool is never sent to a server.
