The main syntax for the IF function in Microsoft Excel is:
IF( condition_here, [value_if_true], [value_if_false] )
If A1 equal to B1
=IF(A1=B1, "value_if_true", "value_if_false")
If A1 not equal to B1
=IF(A1<>B1, "value_if_true", "value_if_false")
If A1 greater than B1
=IF(A1>B1, "value_if_true", "value_if_false")
If A1 less than B1
=IF(A1<B1, "value_if_true", "value_if_false")
If A1 Greater than or equal to B1
=IF(A1>=B1, "value_if_true", "value_if_false")
If A1 Less than or equal to B1
=IF(A1<=B1, "value_if_true", "value_if_false")
