XML Formatter and Validator

XML or Extended Markup Language is a prevalent method to represent structured data on the web. XML was used to transmit messages between client and servers, and it was the defacto standard for web-based APIs, also known as web services. JSON has replaced it, but a lot of legacy APIs still use XML. XML format and validate tools help you validate and pretty-print XML text. That helps human beings read XML more effectively.

Since all conversions use Javascript, it all happens within your system. We do not store your data in our servers. The site uses TLS, so it communicates with the server via an encrypted connection.

The tool is entirely free to use; type or paste XML on the input text area and click on Validate and Format.
