When working with Visual Basic for Applications (VBA), it’s common to encounter situations where you need to compare values or conditions. In such cases, you may find yourself using the “not equal” operator. In this guide, we will explore different ways to express “not equal” in VBA, both formally and informally. We will also provide tips, examples, and cover regional variations if applicable.

Formal Ways to Express “Not Equal” in VBA
When writing code, it’s important to use a language that is clear and concise. In VBA, the formal way to express “not equal” is by using the “Not Equal To” operator, represented by “<>“. Let’s take a look at some examples:
Example 1: If x is not equal to y, do something.
If x <> y Then ' Code to execute when x is not equal to y End If
Example 2: Check if the value in cell A1 is not equal to 10.
If Range("A1").Value <> 10 Then ' Code to execute when A1 is not equal to 10 End If
By using “<>“, you make your code more readable and easily understandable by other developers.
Informal Ways to Express “Not Equal” in VBA
In informal scenarios, developers often resort to alternative ways of expressing “not equal” for brevity or personal preference. While these methods may not adhere to formal coding standards, they are widely used and can be understandable in certain contexts. Here are a few informal ways:
- Using the “!” operator: You can express “not equal” using the “!” operator, which is often associated with negation in some programming languages.
- Combining “Not” and “Equal“: While less concise, you can use the “Not” keyword followed by the “Equal” operator to achieve the same effect.
- Using “<>“: Although mentioned before, the usage of “<>” can also be considered informal in some cases.
Let’s see these informal methods in action:
Example 3: If x is not equal to y, do something.
If x! = y Then ' Code to execute when x is not equal to y End If
Example 4: Check if the value in cell A1 is not equal to 10.
If Not Range("A1").Value = 10 Then ' Code to execute when A1 is not equal to 10 End If
Tips for Using “Not Equal” in VBA
Here are some essential tips to keep in mind when using the “not equal” operator in VBA:
- Ensure both sides of the operator are compatible data types. For example, comparing a numeric variable with a string will likely lead to unexpected results.
- Use brackets when performing complex comparisons to ensure the intended logic is correctly evaluated. For instance, instead of relying solely on operator precedence, enclose subexpressions in parentheses.
- Consider the context of your code. If you’re working within a team or on a collaborative project, it’s best to adhere to established coding conventions to ensure consistency.
- Keep your code readable by using meaningful variable and control names, as well as comments to explain complex conditions or comparisons.
Conclusion
Knowing how to express “not equal” in VBA is crucial for effective coding. In this guide, we explored both formal and informal ways to convey this concept, ensuring code clarity and readability. While the formal “<>” operator is the recommended approach, it’s also important to be aware of informal methods that are widely used in certain programming contexts. By following the tips provided, you’ll be able to confidently compare values and conditions in your VBA code. Happy coding!
