What role does the "Text/Number column" play in Smartsheet?

The "Text/Number column" is a versatile data type in Smartsheet that serves the purpose of capturing and displaying both textual and numerical information. This column type can accommodate a wide range of data entries, making it valuable for organizing information that does not require specific formatting for dates or other more restrictive data types. Users can input descriptive text, numerical values, or a combination of both within this column, allowing for flexibility in managing project details, such as tasks, notes, estimates, or identifiers.

In comparison, the other options refer to functionalities that are not inherent to the Text/Number column. Calculating project costs typically involves using specific formulas applied in number columns, while generating automatic reports and sending notifications are features that Smartsheet offers more broadly through its functionalities and integrations, rather than being directly tied to a specific column type. Therefore, the Text/Number column's primary role is focused on data capture and display, which aligns perfectly with the correct answer.
