Question 1

How do I format or beautify messy XML?

Accepted Answer

Paste your XML into the input box and the tool automatically formats it with proper indentation, making nested elements easy to read.

Question 2

How do I check if my XML is valid?

Accepted Answer

The validator parses your XML in real time and flags syntax errors, such as unclosed tags or malformed attributes, as you type.

Question 3

Can I minify XML to reduce its size?

Accepted Answer

Yes, the minify option strips unnecessary whitespace and line breaks, producing a compact single-line XML string.

Question 4

Can I adjust the indentation level when formatting?

Accepted Answer

Yes, choose your preferred indent size (such as 2 or 4 spaces) to match your project’s coding style.

Question 5

Is this XML formatter free to use?

Accepted Answer

Yes, completely free with no registration required and no limit on how much XML you can format or validate.

Question 6

Does this tool send my XML data to a server?

Accepted Answer

No, all parsing, formatting, and validation happen entirely client-side in your browser — nothing is transmitted anywhere.
