Prepare Data Files

To upload external data from .csv files into a dataset, first prepare your data files.

External data can be loaded into a dataset by preparing two files.

• A data file, which contains the external data, in comma-separated value (CSV) format
• An optional metadata .json file, which describes the structure of the data file

The data and metadata files are used to populate a dataset with the external data. For detailed information about formatting CSV data and JSON metadata, see the External Data Metadata Overview.
