An intelligent cloud data service to visually explore, clean, and prepare data for analysis.
DataPrep (or more accurately Cloud Dataprep by Trifacta) is a visual data transformation tool built by Trifacta and offered as part of Google Cloud Platform.
It is capable of ingesting data from and writing data to several other Google services (BigQuery, Cloud Storage).
Data is transformed using recipes which are shown alongside a visual representation of the data. This allows the user to preview changes, profile columns and spot outliers and type mismatches.
When a DataPrep flow is run (either manually or scheduled), a DataFlow job is created to run the task. DataFlow is Google's managed Apache Beam service.
