Frequently asked questions
What is an XML formatter?
An XML formatter takes raw, unformatted XML and converts it into a readable, indented structure. It makes XML easier to read and debug by adding proper whitespace and line breaks.
Is my data safe?
Yes, completely. Your XML is processed and immediately discarded. We never store, log, or share any data you paste into our tools.
What XML errors can this tool detect?
Our validator detects mismatched tags, unexpected closing tags, and unclosed tags. It highlights exactly which line contains the error.
What is the difference between XML and JSON?
XML uses opening and closing tags like HTML, while JSON uses key-value pairs. XML is more verbose but supports attributes and is widely used in enterprise systems and SOAP APIs.
