About XML

XML (eXtensible Markup Language) is a markup language that defines a set of rules for encoding documents in a format that is both human-readable and machine-readable. XML is commonly used for data exchange between systems, configuration files, and structured document storage.

Frequently Asked Questions

What is XML formatting?

XML formatting, also known as "pretty printing," adds proper indentation, line breaks, and spacing to make XML data more readable. It transforms compressed XML into a structured, easy-to-read format.

What does minifying XML do?

Minifying XML removes all unnecessary whitespace, line breaks, and indentation to create the smallest possible file size. This is ideal for production environments where bandwidth and storage matter.

Is my XML data safe to use with this tool?

Yes, this XML formatter runs entirely in your browser. Your data is never sent to our servers or stored anywhere. All processing happens locally on your device for maximum privacy and security.

What happens if my XML has syntax errors?

The tool will display a clear error message indicating what's wrong with your XML syntax. This helps you identify and fix issues like unclosed tags, invalid characters, or malformed structure.

Can I format large XML files?

Yes, but very large files may slow down your browser since processing happens client-side. For optimal performance, we recommend files under 10MB. Larger files should be processed in chunks.

What's the difference between XML and JSON?

XML uses nested tags for structure while JSON uses key-value pairs and arrays. XML is more verbose but supports attributes and namespaces. JSON is more lightweight and preferred for web APIs.

Do I need to install anything to use this tool?

No installation required! This is a web-based tool that works in any modern browser. Simply paste your XML and start formatting immediately.
