It is a W3C recommendation, and is widely used in the development community for transforming documents into a variety of formats. XSLT is a popular choice for developers due to its flexibility, scalability, and ability to create custom transformation styles. Additionally, XSLT can be used to transform documents into formats that are easier to consume, such as JSON or XML. The language is relatively straightforward to learn and use, making it a great choice for working with XML data. XSLT is an invaluable tool for developers looking to transform data in an efficient and effective way.
