DataWeave in Apex
Enterprise applications often require transformation of data between formats such as CSV, JSON, XML, and Apex objects. DataWeave in Apex complements native Apex support for JSON and XML processing, and makes data transformation easier to code, more scalable, and efficient. Apex developers can focus more on solving business problems and less on addressing the specifics of file formats.
DataWeave is the MuleSoft expression language for accessing, parsing, and transforming data that travels through a Mule application. For detailed information, see DataWeave Overview.
The following are some use-cases for DataWeave in Apex.
- Serializing Apex objects with custom date formats
- Serializing and deserializing JSON with Apex reserved keywords
- Performing custom transformations like removing or adding namespaces or removing __c suffixes
- Parsing and transforming RFC 4180-compliant CSV (Comma-Separated Values) data
You can create a listview for DataWeave resources in your org and view deployed DataWeave scripts within your namespace. From Setup, in the Quick Find box, enter DataWeave, and then select DataWeave Resources. Select the fields that you want to monitor, such as the DataWeave Resource ID, Name, Namespace Prefix, and API Version.
