The Preview Data option runs a pre-check on the selected file(s) to show what data will be extracted. This allows you to check that the file format is correct for the selected project before committing the upload. The grid contains a column for each unit of data that is configured for the project to extract from the data file. Each row in a column represents expected data values for the selected project.
If the grid is empty, confirm that you have the correct project selected and have uploaded the right file type for the project.
External Preprocessors used in the DataSmith Translator are not reflected in the Upload Portal Preview.
Navigating to a different page (home, or back) without submitting any selected files will remove these files from the upload list without submitting the files for processing.
Project
The Project title shows the label of the project that is selected for the upload. If a project is suspended, the flag will appear here also.
Configuration
The Configuration title shows the label of the Config from the DataSmith document used to translate the data file. If more than one Config is enabled for the project, select the label from the dropdown to see the data previewed for a different configuration. Configuration selection here is only for grid population in the preview; the dropdown selection here does not impact how the data file is processed.
Preview Color Codes
Cells are color-coded according to the results of the preprocessing:
| Color | Status | Description |
| Green | Successful | The unit of data is successfully identified for the project. |
| Yellow | Questionable | A unit of data is expected, but is either missing or in an unexpected format. Yellow fields may still be valid, depending on the data file. |
| Blue | No Data | The unit of data will not be processed. |
| Red | Failed Validation | The unit of data did not pass validation conditions. |
