DataWeave: The new way to process CSV files in Salesforce

Are you looking for an easy way to import CSV files into Salesforce without having to write complex code? Then DataWeave is the solution for you.

DataWeave is a new tool from Salesforce that has been available since 2021. It allows you to convert CSV files to usable data formats such as JSON.

Why is DataWeave so useful?

  • It prevents you from having to write more complex code each time to import CSV files. By default, DataWeave already has functionality to read and folder CSV data.
  • It is faster and easier to implement. For example, you can call DataWeave from, say, a Flow. 
  • You save development capacity because you don't have to program as much.

How does DataWeave work?

DataWeave is a standard part of Salesforce, so you don't need to purchase it separately. It is built into most Salesforce licenses, check carefully in advance which edition your organization uses.

To set up DataWeave, there are a few simple steps:

  1. Ask a Salesforce developer to create a DataWeave script. This contains the instructions for converting the CSV data to JSON, for example. The developer can deliver this script within a few hours.
  2. The developer then creates a small Apex class in Salesforce that calls the DataWeave script. This is an adapter of sorts. Again, this takes a few hours at most.
  3. Finally, the developer links the script to an existing process or Flow. For example, to your monthly data import flow. Thus, it automatically calls the DataWeave script as soon as a new CSV file arrives.

And that's it! Your CSV data is now effortlessly converted to a usable format by DataWeave. So all it takes is a few hours of work from a Salesforce developer to do the setup. Then, you can continue to import all CSV files without further modifications.
