XML Formatter & Beautifier

Working with raw, unformatted XML can be incredibly frustrating. Whether you are dealing with API responses, configuration files, RSS feeds, or sitemaps, finding errors or understanding the data hierarchy is difficult when everything is compressed onto a single line. Our XML Formatter & Beautifier solves this problem instantly.

Why Use an XML Formatter?

XML (eXtensible Markup Language) relies heavily on nested tags to represent data structures. When this nesting loses its indentation, the code becomes nearly impossible to read. A reliable XML Formatter restructures your document by adding appropriate line breaks and indentation level for every parent and child element. It reconstructs the visual hierarchy so you can easily trace data flows and locate specific nodes.

Powerful XML Validation

Our formatter doesn't just make your code look pretty; it actively checks it for correctness. Built-in validation parses your XML in real-time, instantly detecting malformed tags, unclosed elements, or invalid characters. If an error is found, the tool highlights the exact line and column so you can fix your syntax before deploying your configuration or sending your payload.

Fast XML Minification

Sometimes you need the opposite of beautification. When transmitting XML over a network or storing it in a database, extra spaces and line breaks just consume unnecessary bandwidth and storage. This tool includes a robust XML Minifier that safely strips out all extraneous whitespace between tags, compressing your XML into a single dense string without corrupting the data structure.

XML to JSON Conversion

Need to transform your XML data into JSON format? Our built-in XML to JSON Converter parses your XML document and outputs clean, properly formatted JSON. This is invaluable when migrating between data formats, integrating with REST APIs, or when you simply prefer JSON's more lightweight syntax.

Interactive Tree View

Visualize the hierarchical structure of your XML with our Tree View mode. Every element, attribute, and text node is displayed in an expandable/collapsible tree, making it easy to navigate deeply nested documents and understand complex data relationships at a glance.

XPath Query Tester

Test XPath expressions against your XML documents in real-time. Our XPath Tester lets you write queries, instantly see matching nodes, and debug your selectors — perfect for web scraping, XSLT development, and data extraction workflows.

Format Presets

Choose from predefined formatting styles — Compact, Readable, Pretty Print, 2 Spaces, 4 Spaces, or Tabs — to match your project's coding standards without manual configuration.

100% Client-Side and Secure

Privacy is critical when working with proprietary data feeds, API keys, or enterprise configurations. That's why our XML Formatter processes everything directly within your web browser. Your data is never transmitted to or stored on any external servers. You get instant, secure formatting with zero latency.
