How to Use XML Formatter & Validator
- Paste or type your XML into the input area, or click an example to get started.
- Choose "Format" to beautify with indentation or "Minify" to strip whitespace.
- If the XML has syntax errors, a descriptive error message is shown instead of output.
- Adjust the indentation size using the dropdown when in Format mode.
- Click "Copy" to copy the result to your clipboard.
Why Format XML?
XML is widely used for configuration files, data interchange, SVG graphics, RSS feeds, and SOAP web services. Unformatted or minified XML can be nearly impossible to read. This tool parses your XML, checks for syntax errors, and re-serializes it with clean, consistent indentation.
Whether you are debugging an API response, editing a configuration file, or inspecting an SVG, properly formatted XML helps you understand the document structure at a glance.
