Which function would you use to count the number of blank cells in a specified range?

The function you would use to count the number of blank cells in a specified range is COUNTBLANK. This function is specifically designed to evaluate a range and return the count of cells that are empty, making it the ideal choice for this task.

In contrast, the other functions serve different purposes: COUNT counts cells that contain numeric data, COUNTA counts all non-empty cells regardless of the type of data they contain, and COUNTIF counts cells that meet a specified condition. Thus, COUNTBLANK is uniquely suited for identifying and tallying empty cells, ensuring accurate results when analyzing data for gaps.
