Supported Data Types

Cloud Dataprep supports the following data types.

Tip: Transforms that include functions work only if the inputs are of a data type and format valid for the function. You should clean up the type and format of your columns before you apply transformations to them.

For more information on how to explicitly reference these data types in your steps, see Valid Data Type Strings.
