Welcome to our comprehensive guide on how to express “not equal to” in Excel formulas! Whether you are a beginner or an advanced user, knowing how to utilize this comparison operator is essential for effective data analysis. In this guide, we will explore the different ways to say “not equal to” in Excel formulas, covering both formal and informal methods, while also highlighting various tips and examples to facilitate your understanding. Let’s dive in!

Using the “ <> ” Operator
The most commonly used and formal way to represent “not equal to” in Excel formulas is by using the “<>” operator. This symbol indicates that the values being compared are not equal.
For example, if you want to check if cell A1 is not equal to B1, you would use the formula =A1<>B1.
Alternative Formal Not Equal To Representations
While the “<>” operator is the standard formal method, Excel also provides a few alternative formal representations for “not equal to”. These include:
- Not Equal To Function: You can use the “NOT()” function in combination with the equal to (“=“) operator. For instance, =NOT(A1=B1) will return TRUE if A1 and B1 are not equal.
- Exact Not Equal To Operator: In some rare cases, you may need to use the “<>=” operator to indicate not equal to or not equivalent to. This is particularly useful when working with text values that may have different formats but still represent the same information.
Informal Ways to Indicate “Not Equal To”
Besides the formal approaches, there are a few informal ways Excel users occasionally express “not equal to” in their formulas. While these may not adhere to standard conventions, they are quite popular and worth mentioning:
Using the “!=” Operator
The “!=” operator, borrowed from programming languages like C++ or Java, has gained some acceptance among Excel users as an informal way to indicate “not equal to” in formulas.
For example, the formula =A1!=B1 will compare whether A1 is not equal to B1, returning either TRUE or FALSE.
Combining Operators
Excel allows combining operators to achieve the “not equal to” condition in a different way. Consider using a combination of the less than (“<“) and greater than (“>“) operators to express “not equal to”.
For example, the formula =(A1<B1) + (A1>B1) will evaluate to TRUE if A1 is not equal to B1, and FALSE otherwise. This technique depends on the fact that the sum of two logical values (1 + 0) will yield 1.
Examples
Let’s explore some examples to solidify your understanding of expressing “not equal to” in Excel formulas.
Example 1:
We want to check if the value in cell A2 is not equal to “Unknown”. The formula to use is:
=A2<>”Unknown”
If the value in A2 is indeed not equal to “Unknown”, the formula will return TRUE.
Example 2:
Suppose we have a dataset where Column A contains numbers and Column B contains names. If we want to determine if the number in A5 is not equal to the name in B5, we can employ the formula:
=A5<>B5
The formula will yield TRUE if both values are not equal to each other, and FALSE otherwise.
Conclusion
Throughout this guide, we have explored the formal and informal methods of expressing “not equal to” in Excel formulas. We started with the standard “<>” operator, and also discussed alternative formal representations such as the “Not Equal To Function” and the “Exact Not Equal To Operator”. Additionally, we touched upon popular informal approaches such as using the “!=” operator borrowed from programming languages, as well as combining operators. By mastering these techniques, you will be equipped to effectively incorporate “not equal to” comparisons in your Excel formulas, enabling advanced data analysis and decision-making.
