When you edit settings on a selected file in the Import Data page, the following settings are displayed.
You can edit any additional or optional settings for an individual dataset. Perform the following:
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.
By default, attempts to interpret the structure of your data during import. This structuring attempts to apply an initial tabular structure to the dataset.
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.
You can apply the column headers to your datasets during import. Select the required option from the drop-down list:
Use first row as header: When selected, the first row is used as the column headers.
No header: When selected, the inference is ignored and column headers are defined using generic names with no headers.
If replacing a file:
Tip: After the dataset is imported, you can rename columns manually or using any row in the dataset. For more information, see Rename Columns.
