There are three modes you can use in Transformation 2.0. The modes are available in a dropdown near the top, left-hand side of the screen.
Three modes
Modify the Input
This mode is useful when you want to make simple targeted changes to source records but keep everything else in the source records as-is.
Create Output Record from Input
This mode is helpful when creating a new output record from the source record. It allows you to define the output record from scratch, so you can pick and choose only the fields you need from the source record. It’s also useful when you want to transform the data from multiple different sources into a canonical format that the flow can then process, making it easier to add new sources in the future.
Create Output Rows from Input
This mode is used when you want to transform record-based data into row-based data. For example, you can transform an object into row-based data to build a CSV file where rows with the same key column must always be kept together in the same file.
