XML (eXtensible Markup Language) is a markup language that is used for storing and transmitting data. It is similar to HTML in structure, but is used for storing data, not for formatting web pages. XML provides a way to describe data using a set of rules, making it easy to transfer data between different systems and platforms.

The XML Formatter tool is used to format and beautify XML code. It makes it easier to read and understand XML code by adding line breaks, indentation, and other formatting options. The tool can also help to clean up messy or poorly formatted XML code, making it easier to maintain and debug.

You can save your formatted XML code in a number of ways. Like most other tools on this website, you can copy the output code to your clipboard and paste it into a text editor. You can also save the formatted XML code to a file on your computer by using the "Save to file" button.

No, there are no limitations to using the XML Formatter tool. You can use it as many times as you need to, and there are no restrictions on the size of the XML code that you can format.
