XML Beautifier: Format and Validate XML Files Online
XML Beautifier parses XML with the browser’s DOMParser, then re-serializes it with indentation for easier reading. It preserves namespaces, CDATA sections, comments, and processing instructions. Choose indentation and options, or use Minify to strip whitespace between tags. Paste or drop XML, review the formatted output, and copy it for documentation, code reviews, or further work.
XML Beautifier is an online XML formatter that parses XML with the browser DOMParser and re-serializes it with indentation. Use this XML Beautifier to make machine-generated documents easier to read, check whether input parses cleanly, or prepare XML for a code review. It formats XML rather than converting it to a different markup or data format.
The tool lets you choose indentation and options, including Minify, which strips whitespace between tags. During re-serialization, namespaces, CDATA sections, comments, and processing instructions are preserved. You can paste or drop XML, review the result, and copy the output for your next task.
XML uses tags to represent structured content, and its nested elements can be difficult to scan when the document is densely written. Beautifying adds indentation to improve readability; minifying strips whitespace between tags for a more compact presentation. These options help when inspecting generated XML, preparing a snippet for discussion, or making changes easier to review in a diff.
XML Beautifier runs entirely in your browser. Your input is processed on your device and is not uploaded, stored, or sent to a server. The tool is free, and once the page has loaded, it continues to work offline without a server connection.
The tool is useful for developers and DevOps engineers who need to inspect XML files, review changes, or check whether input parses cleanly. It can also help anyone preparing XML for documentation, bug reports, or code reviews.
Step 1: Paste or drop your XML into the tool. Use the XML document or snippet you want to format and check.
Step 2: Choose the indentation and options. Select Minify if you want to strip whitespace between tags instead of keeping an indented layout.
Step 3: Review the result after the XML is parsed and re-serialized. If the input does not parse, use the reported line to investigate the problem.
Step 4: Copy the formatted or minified output. You can then use it in a code review, documentation, or your project.
Use case: Make an unreadable, machine-generated XML file easier to review before you commit it. Indentation helps you scan its structure.
Use case: Check whether an XML document you did not write parses cleanly before using it with the specification or process you need to follow.
Use case: Create consistently indented output so a diff is easier to review and whitespace changes are less distracting.
Use case: Format an XML snippet before pasting it into a bug report or code review. The structured output is easier for others to inspect.
Use case: Find the line where an XML parsing problem occurs when a document does not parse cleanly.
Use case: Beautify XML configuration or data files when you need to inspect their structure during development or troubleshooting.
Use case: Minify XML by stripping whitespace between tags when you need a more compact version for further work.
