Which among the following functions provides the total count of all types of entries in a specified range?

The function that provides the total count of all types of entries in a specified range is CountA. This function counts all non-empty cells in a range, including numbers, text, logical values, error values, and any other type of non-empty entry. Therefore, if you want to tally every cell that contains data, regardless of the data type, CountA is the appropriate choice.

In contrast, Count is specifically designed to count only the cells that contain numeric entries. CountIf applies a condition and counts only those cells meeting certain criteria, while Sum is used to add together the numeric values in a range but does not count entries at all. Thus, for the purpose of counting all non-empty entries, CountA is the most suitable function.
