The IFS function checks whether one or more conditions are met, and returns a value that corresponds to the first TRUE condition. IFS can take the place of multiple nested IF statements, and is much easier to read with multiple conditions.
Using IF with AND, OR, and NOT functions in Excel
Following are examples of some common nested IF(AND()), IF(OR()) and IF(NOT()) statements in Excel. 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.

Use nested functions in a formula - Microsoft Support
The following shows an example of using nested IF functions to assign a letter grade to a numeric test score. Copy the example data in the following table, and paste it in cell A1 of a new Excel worksheet.
Use AND and OR to test a combination of conditions
Use AND and OR together or with the IF function. For example, calculate who earns a commission or find data that meets multiple conditions.
