- 2. What is Microsoft Excel? Microsoft Excel is the most popular spreadsheet software. It's used for data entry and management, charts and graphs, and project management. You can format, organize, visualize, and calculate data with this tool. Excel consist of workbooks, in each workbook there is an infinite number of worksheets. These worksheets contains Columns and Rows. The intersection of these columns and rows is called as a cell . The tabs at the bottom of the screen represents different worksheets within a workbook. OVERVIEW OF EXCEL

Zoom control Some parts of the Excel window (such as Ribbon and scroll bars) are standard in most other Microsoft programs. However, other features are more specific to spreadsheets, like the formula bar, worksheet tabs, and name box. The following are the basic parts of the Microsoft Excel Window:
- 11. OPERATION SYMBOLS Addition (+) Subtraction (-) Multiplication (*) Division (/)

- 13. FUNCTIONS
- 14. 1. SUM The SUM() function, as the name suggests, gives the total of the selected range of cell values. It performs the mathematical operation which is addition. As you can see above, to find the total amount of sales for every unit, we had to simply type in the function “=SUM(C2:C4)”. This automatically adds up 300, 385, and 480. The result is stored in C5.
- 15. 2. AVERAGE The AVERAGE() function focuses on calculating the average of the selected range of cell values. As seen from the below example, to find the avg of the total sales, you have to simply type in: “=AVERAGE(C2, C3, C4)” It automatically calculates the average, and you can store the result in your desired location.
- 16. 3. SUBTOTAL Moving ahead, let’s now understand how the subtotal function works. The SUBTOTAL() function returns the subtotal in a database. Depending on what you want, you can select either average, count, sum, min, max, min, and others. In the example above, we have performed the subtotal calculation on cells ranging from A2 to A4. As you can see, the function used is “=SUBTOTAL(1, A2: A4)" In the subtotal list “1” refers to average. Hence, the above function will give the average of A2: A4 and the answer to it is 11, which is stored in C5.
- 17. 4. CONCATENATE This function merges or joins several text strings into one text string. Given below are the different ways to perform this function. In this example, we have operated with the syntax: "=CONCATENATE(A25, " ", B25)"
- 18. 5. UPPER, LOWER, PROPER The UPPER() function converts any text string to uppercase. In contrast, the LOWER() function converts any text string to lowercase. The PROPER() function converts any text string to proper case, i.e., the first letter in each word will be in uppercase, and all the other will be in lowercase.
- 19. 6. NOW() The NOW() function in Excel gives the current system date and time. The result of the NOW() function will change based on your system date and time.
- 20. 7. COUNTIF The function COUNTIF() is used to count the total number of cells within a range that meet the given condition. Below is a coronavirus sample dataset with information regarding the coronavirus cases and deaths in each country and region. Let’s find the number of times Afghanistan is present in the table.
- 21. 8. VLOOKUP VLOOKUP() function. This stands for the vertical lookup that is responsible for looking for a particular value in the leftmost column of a table. It then returns a value in the same row from a column you specify.
