Understanding Objects and Arrays

How to Identify an Object and an Array?
An Object is always enclosed with { } and contains key-value pair. Eg:

{ “name” : “Sravan” }
{ “name” : “Sravan” , “id” : “2”}
{ “Sravan” }
{ “name” : “Sravan” , “2”}


Transforming one data type to other

In Mule 3, we have separate connectors to convert from one type to another. In Mule 4, we use DataWeave to achieve this. DataWeave offers a simple and expressive syntax that allows developers to create complex data transformations easily. It provides a range of built-in functions and operators that make it easy to manipulate data and perform common tasks such as filtering, sorting, grouping, and aggregating data.

Eg :
JSON to XML
XML to JSON
JSON to CSV
