Through the Import Data page, you can upload datasets or select datasets from sources that are stored on connected datastores. From the Library page, click Import Data.

General Limitations

NOTE: For file-based sources, expects that each row of data in the import file is terminated with a consistent newline character, including the last one in the file.

  • For single files lacking this final newline character, the final record may be dropped.



File and path limitations:

Basic Workflow

1. Connect to sources

NOTE: Compressed files are recognized and can be imported based on their file extensions.

Upload: can also load files from your local file system.

Tip: You can drag and drop files from your desktop to to upload them.


NOTE: You can upload a file up to 1 GB in size.



NOTE: When you upload an updated version of a previously uploaded file, the new file is stored as a separate upload altogether. In your flow, you must swap out the old dataset to point to the new one.









For more information on the supported input formats, see Supported File Formats.

2. Add datasets

When you have found your source directory or file:


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 name appears in the interface.

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

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

You can select a single dataset or multiple datasets for import.

Import file settings

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

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 default, applies a specified encoding type on the imported 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. 

NOTE: Assessing the file encoding type based on parsing an input file is not an accurate method. Instead, assumes that the file is encoded in the default encoding. If it is not, you should change the encoding type for the file.


NOTE: In some cases, imported files are not properly parsed due to issues with encryption types or encryption keys in the source datastore. For more information, please contact your datastore administrator.

For a list of supported encoding types, see Supported File Encoding Types.

Detect structure: By default, attempts to interpret the structure of your data during import. This structuring attempts to apply an initial tabular structure to the dataset.

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.

4. Import selections

Single dataset

If you have selected a single dataset for import:

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.

NOTE: If you are importing from multiple files at the same time, the files are not necessarily read in a regular or predictable order.


NOTE: When you import a dataset with parameters from multiple files, only the first matching file is displayed in the right panel.

In the right panel, you can see a preview of each dataset and make changes as needed.

Import Multiple Datasets


If you have selected multiple datasets for import:
