2. Add datasets

When you have found your source directory or file:

  • You can hover over the name of a file to preview its contents.

    Info

    NOTE: Preview may not be available for some sources, such as Parquet.

  • Click the Plus icon next to the directory or filename to add it as a dataset.

    Tip

    Tip: You can import multiple datasets at the same time. See below.

  • Excel files: Click the Plus icon next to the parent workbook to add all of the worksheets as a single dataset, or you can add individual sheets as individual datasets. See See Import Excel Data.


3. Configure selections

When a dataset has been selected, the following fields appear on the right side of the screen. Modify as needed:

  • Dataset Name: This  This name appears in the interface.
  • Dataset Description: You  You may add an optional description that provides additional detail about the dataset. This information is visible in some areas of the interface.

    Tip

    Tip: Click the Eye icon to inspect the contents of the dataset prior to importing.

...

You can modify settings used during import for individual files. In the card for an individual dataset, click click Edit Settings.

Info

NOTE: In some cases, there may be discrepancies between row counts in the previewed data versus the data grid after the dataset has been imported, due to rounding in row counts performed in the preview.

  • Per-file encoding: By  By default, 
    D s product
    attempts  attempts to interpret the encoding used in the file. In some cases, the data preview panel may contain garbled data, due to a mismatch in encodings. In the Data Preview dialog, you can select a different encoding for the file. When the correct encoding is selected, the preview displays the data as expected. 
  • Detect structure: By  By default, 
    D s product
    attempts  attempts to interpret the structure of your data during import. This structuring attempts to apply an initial tabular structure to the dataset.
    • Unless you have specific problems with the initial structure, you should leave the Detect structure setting enabled. Recipes created from these imported datasets automatically include the structuring as the first, hidden steps. These steps are not available for editing, although you can remove them through the Recipe panel. See See Recipe Panel.
    • When detecting structure is disabled, imported datasets whose schema has not been detected are labeled, unstructured datasets. When recipes are created for these unstructured datasets, the structuring steps are added into the recipe and can be edited as needed.
    • For more information, see see Initial Parsing Steps.
  • Remove special characters from column names: When selected, characters that are not alphanumeric or underscores are stripped, and space characters are converted to underscores.

    For more information, see Sanitize Column Names.

If you have selected a single dataset for import:

...

  • Click Continue. The dataset is imported. 
  • A recipe is created for it, added to a new flow, and loaded in the Transformer page for wrangling.

...

Multiple datasets

You can import multiple datasets from multiple sources at the same time. In the Import Data page, continue selecting sources, and additional dataset cards are added to the right panel.

...

  • To import the selected datasets, click Import Datasets. The imported datasets are created. You can begin working with these imported datasets now or at a later time. If you are not wrangling the datasets immediately, the datasets you just imported are listed at the top of the Library page. See Library Page.To import the selected datasets and add them to a flow:
  • Click the Add Dataset to a Flow checkbox.
  • Click the textbox to see the available flows, or start typing a new name.
  • Click Import & Add to Flow.
  • Create or select the flow to which to add them:

    1. Filter by Type: Click one of the tabs in the dialog to display only the applicable flows. 
    2. Search: Start typing letters to filter the list of flows.
    3. Create new flow: Enter a name and description for the new flow to which to add the datasets.
    4. To add the datasets to the selected flow, click Add.
  • The datasets are imported, and the associated recipes are created. These datasets and recipes are added to the selected flow.
  • For any dataset that has been added to a flow, you can review and perform actions on it. See click Continue
  • The datasets are imported and added to a new flow.

    Info

    NOTE: To rename this flow, click Untitled at the top of Flow View.

    Tip

    Tip: To begin transforming one of these datasets, select it. From its context menu, select Add new recipe. Select the recipe. In the context panel on the right, select Edit Recipe. See Transformer Page.

    For more information, see Flow View Page.

  • To remove a dataset from import, click the X in the dataset card.
