Data Loader and Import Wizard are two Salesforce tools designed for importing, exporting, and updating data. However, there are some key differences between the two:
Data Volume: Import Wizard allows users to load up to 50,000 records at a time, while Data Loader supports the loading of millions of records.
Object Support: Data Loader supports all objects and all data types, including standard and custom objects, while Import Wizard has limited support for objects and data types.
Data Manipulation: Import Wizard cannot manipulate data and requires that any data updates be done via an Upload and Update workflow. Data Loader, on the other hand, allows for complex transformations and data manipulation through its mapping and transformation feature.
File Format: Import Wizard can only imports .csv files, while Data Loader can work with a variety of file formats.
Advanced Features: Data Loade offers several advanced features, including batch processing, command-line operation, and server-based automation. Import Wizard, however, lacks these advanced features.
Overall, Import Wizard is an easy-to-use tool for quickly importing small amounts of data into Salesforce, while Data Loader is a power tool with advanced features that allows for high-volume, complex data management needs.
