See "Converted file formats" below.

Notes on JSON:

There are two methods of ingesting JSON files for use in the product. 

• JSON v2 - This newer version reads the JSON source file through the Conversion Service, which stores a restructured version of the data in tabular format on the base storage layer for quick and simple use within the application. 

  Tip
  Tip: This method is enabled by default and is recommended. For more information, see Working with JSON v2.

    

• JSON v1 - This older version reads JSON files directly into the platform as text files. However, this method often requires additional work to restructure the data into tabular format. For more information, see Working with JSON v1.
