Data Loader is a versatile tool that enables users to import, export, update, delete, and manage large volumes of data within Salesforce. A key capability of Data Loader is its ability to handle both one-time and scheduled data imports. This feature is particularly useful for regularly scheduled data updates, such as daily imports of data from external systems or periodic data cleansing activities.
Salesforce documentation confirms that Data Loader allows scheduling for regular imports or exports, making it an efficient tool for managing data over time. However, it does not include native features to prevent duplicates or import metadata, as it primarily focuses on data records.
