If you want to do something specific when a cell is NOT this or that (i.e. is NOT equal to X or Y, etc.) you can use the IF function in combination with the NOT and OR functions to run a test, then take one action if the result is TRUE, and (optionally) do something else if the result of the test is FALSE.
If color is NOT red or green
In the example shown, we simply want to "mark" or "flag" records where the color is not either red OR green. In other words, we want to check cells in column B, and then take action if they contain a value other than t"red" or "green".
This snippet will return TRUE if the value in B6 is not "red" OR not "green" and FALSE if not.
Since we want to flag items that pass our test, we need to take an action when the result of the test is TRUE. In this case, we do that by adding an "x" to column D. If the test is FALSE, we simply add an empty string (""). This causes an "x" to appear in column D when the value in column B is either "red" or "green" and nothing to appear if not.*
You can extend the OR function to check additional conditions as needed.
*If we didn't add the empty string when FALSE, the formula would actually display FALSE whenever the color is not red.
Increase price if color NOT red or green
If you need to do something more complex, just extend the formula.
For example, say you want to increase all colors except red and green by 15%. In that case, you could use this formula in column E to calculate a new price:
If you want to do something specific when a cell equals a certain value, you can use the IF function to test the value, then do something if the result is TRUE, and (optionally) do something else if the result of the test is FALSE. If color is red,...
If you want to do something specific when two or more conditions are TRUE, you can use the IF function in combination with the AND function to evaluate conditions with a test, then take one action if the r esult is TRUE, and (optionally) do...
The IF function can perform a logical test and return one value for a TRUE result, and another for a FALSE result. For example, to "pass" scores above 70: =IF(A1>70,"Pass","Fail"). More than one condition can be tested by nesting IF functions....
The OR function is a logical function to test multiple conditions at the same time. OR returns either TRUE or FALSE. For example, to test A1 for either "x" or "y", use =OR(A1="x",A1="y"). The OR function can be used as the logical test inside the...
In this video we look at how to combine the IF function with the OR and AND functions to test more than one condition at the same time.
