Excel Tutorial – NOT

The NOT function in Microsoft Excel is a logical function that allows you to reverse the logical value of a cell or a logical test. This can be helpful for tasks such as data validation or error checking.

Here’s how to use the NOT function:

1. Open a blank Excel spreadsheet.
2. In the cell where you want to display the result of the NOT function, type the following formula: =NOT(value)
3. Replace “value” with the cell reference or value that you want to reverse. The value can be a logical test, such as a comparison between two values or a test for a specific value.
4. Press Enter to calculate the result. The result will be the reverse of the original value. For example, if the original value was TRUE, the result will be FALSE, and if the original value was FALSE, the result will be TRUE.

Here are a few examples of how you might use the NOT function:

• Reverse the value of a cell: =NOT(A1)
• Reverse the result of a logical test: =NOT(A1>10)
• Reverse the result of a function: =NOT(ISNUMBER(A1))
