This formula says that if the number of days in the year is equal to 366, then display the text "Leap Year!" and otherwise display the text "Regular Year." =IF(A1>365, "Leap Year!", "Regular Year") There are numerous ways this can be accomplished with logical operators. You wanted to write an IF statement to display the text "Leap Year!" if there are 366 days in the year, and display the text "Regular Year" if there are 365 days in the year. Say you had the following spreadsheet and cell A1 contained the number of days in a given year. These operators are used in the IF function, SUMIF function, COUNTIF function, and others. In Excel, logical operators form the basis for all logic and decision making when writing a formula. Using Logical Operators With IF Statements To test whether two strings of text are exactly the same (including capitalization) use the EXACT function. This statement is true because the equal to operator is not case-sensitive, so it considers the two strings of text to be equivalent, even though they have differing capitalization. This means that it considers two strings of text to be equal as long as the letters are the same regardless of capitalization. The equal to operator in Excel is not case-sensitive when used on text. Is the Equal To Operator In Excel Case-Sensitive? 3/4 and 0.75 are numerically equivalent values, so they are equal to one another. This statement is true even though the values don't look the same. This statement is false because the words are not exactly the same, even though they are very similar. This statement is true because the two strings of text are exactly the same. This statement is false because the values are not exactly equal, even if they are very close. This statement is true because 5 is exactly equal to 5. If they are not the same, the statement will be false. This applies to both numerical and text values. Otherwise, return the original price.The equal to operator states that the values on each side of it are exactly equal. Translation: if the color is NOT "Red" or "Green", increase the price by 15%. To perform this task, the formula in E6 below is: =IF(NOT(OR(B6="red",B6="green")),C6*1.15,C6) If the color is Red or Green, you want to leave the price alone. For example, let's say you want to increase the price for all colors except Red and Green by 15%. You can use other formulas inside the IF function to run a different calculation instead of simply returning "x". This argument is not required, but if we leave it empty, the formula will return FALSE when a color is "Red" or "Green". Also, notice that we need to provide an empty string ("") for the false result. The expressions B6="red", B6="Red", and B6="RED" will all return the same result. Keep in mind that Excel is not case-sensitive by default, so the color names in the formula are all lowercase. This causes an "x" to appear in column D when the color in column B is NOT "Red" or "Green". You can extend the OR function to check additional conditions as needed. Since we don't want to display anything for other values, we provide an empty string ("") for value_if_false. The rest of the formula is standard. Since we want to flag items that pass the test, we provide "x" for value_if_true. Adding NOT means the test will return TRUE if B6 is NOT "Red" or "Green", and FALSE otherwise: NOT(OR(B6="red",B6="green")) The NOT function simply reverses this result. OR will return TRUE if B6 is "Red" or "Green", and FALSE if B6 contains any other value. Working from the inside out, we first use the OR function to test for "red" or "green": OR(B6="red",B6="green") In this formula, the logical test is this bit: NOT(OR(B6="red",B6="green")) If the color is "Red" or "Green" we don't want to do anything. In the worksheet shown, the goal is to mark records where the color is NOT "Red" OR "Green" with an "x". Translation: If the value in A1 is NOT greater than 100, then return "OK". For example, to reverse the existing logic in the formula above, we can add NOT like this: =IF(NOT(A1>100),"OK","Fail") The behavior of the IF function can be easily extended by adding functions like AND, OR, and NOT to the logical test. In this formula, A1>100 is the logical test. For example, to return "OK", when a value is over 100 and "Fail" if not, you can use the IF function in a formula like this: =IF(A1>100,"OK","Fail") The IF function is commonly used for simple tests. If the color is "Red" OR "Green", we want to display nothing. More specifically, we want to check the color in column B, and leave an "x" in rows where the color is NOT "Red" OR "Green". The goal is to "flag" records that are neither "Red" nor "Green".
