XML Formatterv1.0.0

Paste or type raw XML into the input field and click Format to produce clean, properly indented output. The tool parses your XML using the browser's built-in DOMParser, applies the configured indentation level, and optionally sorts element attributes in alphabetical order. All settings and input persist automatically between sessions using localStorage, so you can return to your work at any time without losing progress.

• Paste your raw or minified XML into the XML Input field. The tool accepts any valid XML document, fragment, or configuration file.
• Click the Format button to generate the beautified output. Formatting also triggers automatically after a brief pause while typing.
• Open the Settings panel to adjust the Indent Size (number of spaces per nesting level, default is 2). Set it anywhere from 1 to 16 spaces depending on your project conventions.
• Enable Sort Attributes Alphabetically in the settings panel to reorder attributes on each element in alphabetical order by attribute name. This produces consistent attribute ordering across documents.
• Review the formatted result in the Formatted XML Output field. Click Copy to Clipboard to copy the result for use in your editor, API request, or documentation.
• Click Reset to clear all input, output, and saved settings, restoring every field to its default state.
• Numeric inputs such as Indent Size accept fractions (3/4), mixed numbers (1 1/2), decimals (2.5), and scientific notation (2e0). The tool rounds to the nearest whole number for indentation.

Minified or single-line XML hides its structure, and reindenting it exposes the nesting, missing tags, and attribute values that matter during debugging and review. The scenarios below show where consistent indentation and sorted attributes turn dense markup into a document a person can read and compare.

• API Development: Paste raw XML responses from REST or SOAP endpoints to inspect nested elements, verify data structures, and identify missing or malformed tags before integrating with client applications.
• Configuration Management: Format application configuration files such as Maven pom.xml, Spring XML beans, or Android manifest files to ensure consistent indentation across teams and version control systems.
• Data Engineering: Beautify XML data exports from databases, ETL pipelines, or reporting tools to review record structures, validate schema compliance, and prepare documentation for data dictionaries.
• Technical Writing: Format XML code samples for inclusion in technical documentation, tutorials, and API reference guides. Consistent indentation and sorted attributes improve readability for end users.
• Quality Assurance: Compare formatted XML output from different environments or test runs by normalizing indentation and attribute order. Sorted attributes eliminate false positives in diff comparisons caused by attribute reordering.
• Education: Provide students with a quick way to visualize XML document structure. Adjustable indentation helps learners understand nesting depth and parent-child relationships in markup languages.
• DevOps and CI/CD: Validate and format XML pipeline configurations, deployment descriptors, and infrastructure-as-code templates. Ensure that committed files follow team formatting standards before code review.
