What Is Excel’s ISBLANK Function?
Excel’s ISBLANK function is a logical function that returns “TRUE” if a cell is blank and “FALSE” if it contains any value, excluding empty strings. It is commonly used in Excel formulas and conditional formatting to check if a cell is empty or not. The syntax for the ISBLANK function is as follows:
Where “value” is the cell or range that you want to check for blank cells. The function returns a Boolean value of “TRUE” or “FALSE” based on whether the selected cell or range of cells is blank or not.
Here is an example of how to use the ISBLANK function to check if a cell is blank:
This formula returns “TRUE” since cell A2 is blank. If cell A2 contains any value, even an empty string, the function will return “FALSE”.

IF With ISBLANK

In this example, the IF function checks whether cell A2 is blank using the ISBLANK function. If A2 is blank, the function returns anN/A. If A2 is not blank, the function returns the value of A2 multiplied by 2.
FILTER With ISBLANK
The ISBLANK function and the FILTER function can be used together in Excel to filter based on whether a cell is blank or not. Here’s an example:
Let’s say you have a table with two columns:NameandEmail. You want to filter the table to show only rows where the Email column is blank. You canuse the FILTER functionwith ISBLANK as follows:
In this formula,A2:B8is the range of cells you want to filter, andB2:B8is the range of cells you want to check for blanks. This formula will return only the rows without emails, filtering out all other rows.
