To check if the given number is integer or not, here are some formulas may help you. Please do as follows:

1. In a blank cell, please type this simple formula: =int(A1)=A1, see screenshot:

doc-check-if-integer-1

2. Then drag the fill handle over to the cells that you want to apply this formula, and the integer cells and blank cells are displayed as True, other cells are displayed as False, see screenshot:

doc-check-if-integer-2

Note:

With above formula, the blank cells are also displayed True, if you want to ignore the blank cells, here is another formula: =IF(LEN(A1),MOD(A1,1)=0,""), then press Enter key and copy down the formula to the cells you need, you will get the following result:

doc-check-if-integer-3
