Understanding their capabilities, differences, and best-use cases is crucial for efficient data management within Salesforce. This article provides an in-depth comparison of these tools and highlights important considerations when importing and exporting data.

❌ Only supports importing, not exporting or deleting records and limited standard Object.
❌ Limited to 90 fields per record and a maximum record size of 400KB.
❌ Only one import job can be run at a time.


Salesforce Data Loader

Other Methods of Importing and Exporting Data in Salesforce

Apart from Data Import Wizard and Data Loader, there are other ways to handle data in Salesforce:

Important Considerations When Importing Data

To ensure smooth data import, keep the following points in mind:

Multi-Select Picklists

  • Use semicolons (;) to separate multiple values in the import file.

Checkbox Fields

  • Use 1 for checked values and 0 for unchecked values.

Default Values

  • If a picklist, multi-select picklist, or checkbox field is not mapped, the default value (if set) will be automatically inserted.

Date/Time Fields

  • Ensure that date/time format matches your Salesforce locale settings.

Formula Fields

  • Read-only fields cannot be imported; they are calculated automatically.

Field Validation Rules

  • Salesforce enforces field validation rules, so ensure that the imported data complies with these rules.

Universally Required Fields

  • Required fields must be included in the import file, or the import will fail.

Conclusion

Both Data Import Wizard and Data Loader serve essential roles in Salesforce data management. The Data Import Wizard is ideal for small-scale imports with a user-friendly experience, while the Data Loader is better suited for large data volumes and more complex data operations. Understanding the differences will help you choose the right tool for your data needs in Salesforce.

By following best practices and leveraging the right tool for your use case, you can efficiently manage your Salesforce data without errors or duplication.
