The Salesforce Data Import Wizard is a tool designed for importing data into Salesforce, providing a user-friendly interface for non-technical users to integrate external data with their Salesforce environment. It supports the import of various entities, including accounts, contacts, leads, and custom objects, but has limitations such as not supporting delete operations, Cases, and Opportunities, and no data export capabilities. In contrast, the Salesforce Data Loader is a more advanced tool that supports bulk importing or exporting of data into or out of Salesforce, offering a wider range of operations, including insert, update, upsert, delete, and hard delete, but has limitations such as requiring installation, not supporting scheduled exports, and lacking native duplicate handling. The choice between the two tools depends on the specific needs and scenarios, with the Data Import Wizard being suitable for smaller-scale tasks that require user-friendly guidance and the Data Loader being ideal for more complex and larger volume data tasks. Additionally, CData Sync is introduced as a tool for building reverse ETL pipelines from SQL Server database and Snowflake data warehouses into Salesforce.
