 can read and import directly these file formats:

  • Excel (XLS/XLSX)CSV
  • JSON v1, including nested

    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.

Info

NOTE: Compressed files that require conversion of the underlying file format are not supported for use in the product.

Converted file formats:

  • Excel (XLS/XLSX)

    Tip

    Tip: You may import multiple worksheets from a single workbook at one time. See Import Excel 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.
