Determining an Integer Value in Excel

When working with data in Microsoft Excel, you may find yourself needing to determine whether a particular cell contains an integer value. This can be accomplished using a simple formula. To start, select the cell or range of cells that you want to check for integer values. Then, enter the following formula:


This formula will return TRUE if the value in cell A1 is an integer, and FALSE if it is not. You can then use this information to apply conditional formatting, or take other actions based on the results of this formula.

Keep in mind that this formula only checks for integer values; it will not work for non-integer values such as decimals or fractions. If you need to check for those values as well, you can use a different formula:


This formula will return TRUE if the value in cell A1 is a number, and is also equal to the nearest integer value. For example, if cell A1 contains the value 3.14159, this formula would return FALSE, since 3.14159 is not equal to 3 (the nearest integer value). However, if cell A1 contained the value 3.5, this formula would return TRUE, since 3.5 is equal to 3.
