Salesforce standard imports are very difficult and time-consuming. The functionality is limited too – you can’t reject imports after they’ve begun and you can’t reverse them easily if there are any issues.
If you use the free version of MuleSoft Data Loader to do a data import, there’s no guarantees on data security.
You can alternatively pay for MuleSoft's Professional or Enterprise editions which range in price between $99-$299 per month per user.
With Workbooks you don’t need to worry complicated data imports. You can easily run them from within the platform at no additional cost.
You can also reject an import up to 30 days after it began. You can review, inspect, and abort at any time during those 30 days.
