What functionality does the 'Data Shuttle' feature provide in Smartsheet?

The 'Data Shuttle' feature in Smartsheet is designed to streamline the process of transferring data between Smartsheet and external data sources, making option B the correct answer. This capability allows users to set up automated workflows that can extract data from various sources, such as spreadsheets or databases, and load it directly into Smartsheet, or vice versa. This automation facilitates easier data management, reduces the burden of manual data entry, and helps ensure that the information in Smartsheet is always up-to-date and accurate.

The other functionalities mentioned do not align with what 'Data Shuttle' specifically offers. While data visualizations are crucial for analyzing data, they are not the primary purpose of this feature. Similarly, generating automated reports is a separate function meant for summarizing data in a report format, which does not involve direct data movement. Merging multiple sheets into one is also not a feature of 'Data Shuttle'; rather, that is a separate capability in Smartsheet for consolidating information from different sheets.
