So in this lesson, we'll look at how to apply the formatting to cells containing all dates in the past, not just those in the last month. These are simple and easy to apply but the problem for our scenario is that there isn't a built-in conditional formatting rule that applies to all dates in the past - the best you can do with the built-in rules is to format cells containing dates that are in the last month. Note that Excel's Conditional Formatting feature includes an option to highlight dates according to a range of pre-configured conditional formatting rules. Second, it extends the criteria for the formatting rule so that only those tasks where the due date is in the past AND the task is still open will be highlighted - at a glance, we can tell which tasks are overdue and need attention.First, it shows you how to apply a format to a cell containing a date where that date is in the past - this allows us to see which of the tasks in our project are overdue.
This lesson uses a Project Checklist example to demonstrate how to use Conditional Formatting. You can even use the value of other cells in the worksheet as part of your conditional formatting criteria. It allows you to apply formatting to cells or ranges of cells based on criteria that you can choose. If you were to change the formula to =NOT(B2>A5) it would return TRUE and the cell would be formatted.Excel's Conditional Formatting feature is incredibly powerful. In this case A5 is greater than B2, so the result will return FALSE. If A5 is NOT greater than B2, format the cell, otherwise do nothing. If A2 is greater than B2, format the cell, otherwise do nothing.
Using the earlier Dates example, here is what the formulas would be. Next, select the “ Use a formula to determine which cells to format” option, enter your formula and apply the format of your choice. When you do this you can omit the IF function and use AND, OR and NOT on their own.įrom the Home tab, click Conditional Formatting > New Rule. You can also use AND, OR and NOT to set Conditional Formatting criteria with the formula option. Using AND, OR and NOT with Conditional Formatting In this case, A5 is greater than B2, so the formula returns FALSE. IF A5 is not greater than B2, then return TRUE, otherwise return FALSE. 03/12/14 is greater than 01/01/14, so the formula returns TRUE. IF A2 is greater than B2, return TRUE, otherwise return FALSE. Here are some examples of using AND, OR and NOT to evaluate dates. You can also substitute Text or Numeric values for the TRUE/FALSE values to be returned in the examples.
The remaining True/False arguments are then left as part of the outer IF statement. Note that all of the examples have a closing parenthesis after their respective conditions are entered. IF A7 (“Blue”) is NOT equal to “Red”, then return TRUE, otherwise return FALSE. In this case 25 is not greater than 50, so the formula returns TRUE. IF A6 (25) is NOT greater than 50, then return TRUE, otherwise return FALSE. Here are the formulas spelled out according to their logic: The NOT function only takes one condition. The AND and OR functions can support up to 255 individual conditions, but it’s not good practice to use more than a few because complex, nested formulas can get very difficult to build, test and maintain. NOT – =IF(NOT(Something is True), Value if True, Value if False)įollowing are examples of some common nested IF(AND()), IF(OR()) and IF(NOT()) statements. OR – =IF(OR(Something is True, Something else is True), Value if True, Value if False) When you combine each one of them with an IF statement, they read like this:ĪND – =IF(AND(Something is True, Something else is True), Value if True, Value if False) Here are overviews of how to structure AND, OR and NOT functions individually. The value that you want returned if the result of logical_test is FALSE. The value that you want returned if the result of logical_test is TRUE. IF(NOT()) - IF(NOT(logical1), value_if_true, )) Use the IF function along with AND, OR and NOT to perform multiple evaluations if conditions are True or False.
