Forget about serialization formats and focus on your logic: DataWeave will handle the specifics of JSON, XML, CSV, YAML, and many more.

"firstName": "John",
"lastName": "Smith",
"age": 45
},
{
"firstName": "Jane",
"lastName": "Doe",
"age": 34
}

%dw 2.0 output csv --- payload

Navigate through your data in a structural way by combining DataWeave selectors. Values, keys, attributes, namespaces… no matter how nested, are just a query away.
language: DataWeave content: description: Transform data! resources: - Interactive Tutorial - Playground - VSCode extension - CLI - Community
%dw 2.0 output json --- payload.content.resources[0 to 1]
[ "Interactive Tutorial", "Playground" ]
Leverage data from multiple sources to create a brand new structure of your own. Simply define your structure and combine multiple queries.
<order> <product> <name>MuleSoft Connect</name> </product> <product> <name>Dreamforce</name> </product> <buyer> <name>Michael</name> <city>San Diego</city> <address>Koala Boulevard 314</address> </buyer> </order>
%dw 2.0 output json --- { tickets: payload.order.*product.name, deliverTo: { address: payload.order.buyer.address, city: payload.order.buyer.city } }
{
"tickets": [
"MuleSoft Connect",
"Dreamforce"
],
"deliverTo": {
"address": "Koala Boulevard 314",
"city": "San Diego"
}
}
Combine functions to completely reshape your data. Our standard library covers filtering, mapping, grouping, reducing, and many other common patterns.
