How to Check Null Value in Excel In Microsoft Excel, a null value represents an empty cell or a cell that has no defined value. It is different from a blank cell, which appears empty but contains a space character. Null values can arise due to various reasons, such as data import errors, incomplete data entry, or formula calculations.
Importance of Identifying Null Values Null values can lead to errors and incorrect results in Excel formulas and calculations. It is essential to identify and handle null values appropriately to ensure data integrity and accurate analysis.
