Definition
DataWeave Resources is a Setup page for managing DataWeave scripts, which are used for data transformation within Salesforce. DataWeave is a programming language for querying and transforming data available in Mule applications and Salesforce, allowing developers to convert data between formats like JSON, XML, and CSV.
In plain English
“Here's a simple way to think about it: DataWeave Resources brings MuleSoft's data transformation language inside Salesforce. JSON to XML, CSV reshape, format conversion - declarative transforms that would take significant Apex to express otherwise.”
Worked example
A developer at CloudServe creates a DataWeave Resource to transform incoming XML order data from their ERP system into the JSON format expected by Salesforce REST APIs. The script maps nested XML elements to flat Salesforce fields, handles date format conversions, and filters out test orders, all in a few lines of declarative DataWeave code.
Why DataWeave Resources brings MuleSoft's transformation language inside Salesforce
DataWeave is MuleSoft's expression language for transforming data - JSON to XML, CSV to a custom JSON shape, one structure into another. DataWeave Resources is the Setup page that brings DataWeave scripts inside Salesforce, where they can be invoked from Apex. The result is a declarative transformation layer for cases where Apex's manual JSON parsing or XML manipulation would otherwise dominate the logic.
The reason it's worth knowing about is that data transformation is a recurring problem in any integration-heavy org. Mapping inbound webhook payloads to Salesforce records, formatting outbound API requests, parsing complex CSV imports - DataWeave handles them with a fraction of the code Apex would need. Use it where the transformation logic is non-trivial; reach for plain Apex when the data shape is simple enough that DataWeave would be overkill.
How organizations use DataWeave Resources
Inbound webhook payloads (variable JSON shapes) get normalized via DataWeave before Apex consumes them - the pre-transform code is half the size of the alternative.
Outbound API requests use DataWeave to format Salesforce data into the partner-required structure - no hand-coded JSON building.
Complex CSV imports use DataWeave for header reshaping; the transform handles 12 source-system formats with one parameterized script.
