  Info
  NOTE: Excel import is supported through file upload only.

  Tip
  Tip: You may import multiple worksheets from a single workbook at one time. See Import Excel Data in the User Guide.

• CSV
• JSON, including nested

  JSON files can be read natively but often require additional work to properly structure into tabular format. Depending on how the D s webapp is configured (v1 or v2), JSON files may require conversion before they are available for use in the application. See "Converted file formats" below.

  
  

  Info
  NOTE: D s product requires that JSON files be submitted with one valid JSON object per line. Consistently malformed JSON objects or objects that overlap linebreaks might cause import to fail. See Initial Parsing Steps in the User Guide

• Plain Text
• LOG
• TSV

• Parquet

  Info
  NOTE: When working with datasets sourced from Parquet files, lineage information and the $sourcerownumber reference are not supported.

Converted file formats

Files of the following type are not read into the product in their native format. Instead, these file types are converted using the Conversion Service into a file format that is natively supported, stored in the base storage layer, and then ingested for use in the product.

Converted file formats:

• Excel (XLS/XLSX)

  Info
  NOTE: Other Excel-related formats, such as XLSM format, are not supported.

  
  

  Tip
  Tip: You may import multiple worksheets from a single workbook at one time. See Import Excel Data in the User Guide.

• PDF

  • PDF is supported for import only.
  • See Import PDF Data in the User Guide.

• JSON v2

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.
