Dataloader.io is a popular data import and export tool designed specifically for Salesforce. It is a product by MuleSoft, a company that provides integration solutions. Dataloader.io allows Salesforce users to easily import, export, and delete data in bulk from their Salesforce org using a user-friendly web-based interface.

Key features of Dataloader.io for Salesforce include:

1. Data Import: Users can use Dataloader.io to import data from various sources into their Salesforce org. It supports importing data in various file formats, such as CSV, Excel, and XML, and allows mapping the fields in the source file to the corresponding fields in Salesforce.

2. Data Export: Dataloader.io enables users to export data from Salesforce to external files in formats like CSV, Excel, or JSON. This is useful for backing up data or generating reports for analysis.

3. Data Update and Upsert: Users can use Dataloader.io to update existing records in Salesforce or perform upsert operations, which update records if they already exist or insert them if they are new.

4. Data Deletion: Dataloader.io allows users to delete records in bulk from Salesforce. It is essential to use this feature with caution, as data once deleted cannot be recovered.
