What Is the ISBLANK Function in Excel?
Excel’s ISBLANK function lets you check if the specified cell is blank or not. If the cell is blank, the function retrieves a TRUE value. If the cell is not blank, you get a FALSE value. You can use these values with other Excel functions, like IF , to perform actions on or in response to your blank and non-blank cells.
The syntax of the ISBLANK function is:
=ISBLANK(value)
Here, value refers to the reference of the cell that you want to check. So if you want to check whether or not cell A1 is blank, you would insert A1 in place of value.
Excel also offers other functions for working with blank cells, like COUNTBLANK that gives you the total count of blank cells in the specified range. If you already know whether a cell is blank or not but want to know what type of value it contains, you can use functions like ISNUMBER to check if a specified cell contains any numbers, or ISTEXT to check if a cell has a text value.
Check If a Cell Is Blank With Excel’s ISBLANK Function
To use the function, first, open your spreadsheet with the Excel app and click the cell where you want to display the function’s result.
In the selected cell, type the following function and press Enter. In this function, replace C2 with the cell that you want to check.
=ISBLANK(C2)
To use the function for all your records in the spreadsheet, from the bottom-right corner of the cell where you entered the function, drag downwards covering all your rows.
Now you know what cell is and isn’t blank in your spreadsheet.
