Several new functions are added in the math and trigonometry, statistical, engineering, date and time, lookup and reference, logical, and text function categories. Also, Web category is introduced with few Web service functions.

Functions by Category

Excel functions are categorized by their functionality. If you know the category of the function that you are looking for, you can click that category.

Step 1 − Click on the FORMULAS tab. The Function Library group appears. The group contains the function categories.

Step 2 − Click on More Functions. Some more function categories will be displayed.

Step 3 − Click on a function category. All the functions in that category will be displayed. As you scroll on the functions, the syntax of the function and the use of the function will be displayed as shown in the image given below.
