Final answer:
The data loader provides additional functionality such as exporting or deleting data, choosing whether to run data validation rules, and saving mappings for later use.
Step-by-step explanation:
An administrator might use the data loader rather than import wizard for several reasons:
- Option 1: Export or delete data: The data loader allows you to export data from Salesforce and delete existing data, which the import wizard does not offer.
- Option 2: Choose whether or not to run data validation rules: The data loader gives you the flexibility to choose whether to run data validation rules during the import process.
- Option 4: Save mappings for later use: With the data loader, you can save the mappings between source and target fields, so you don't have to manually map them every time you import data.
