How to Check If a Cell Is Empty in Excel Program?

In large complex spreadsheets, locating empty cells requires more than a glance. There are many methods available to make the task of identifying empty cells easier. They include the three function methods called ISBLANK, LEN and IF.

Just a few clicks on the keyboard using the right Excel function can save you hours of time.

The ISBLANK function returns the logical value of TRUE if the cell is empty. The LEN function returns a value containing the number of characters in a string or the number of bytes required to store a variable in a cell. If a cell is blank, that value will be zero according to Microsoft. You can use the IF function with empty quotes (“”) to test for empty cells.

To clarify the formula examples, “B2” represents the cell containing the data you want to test. “E2” represents the cell in which you enter the formula. Use the values of your data in place of these cell addresses. To keep your formulas simple, If your headers are on a row, the row numbers should match, if your headers are on a column, the column letters should match.
