EXCEL FORMULAS

Excel offers a wide range of formulas and functions to perform various calculations and operations. Here are some commonly used Excel formulas:

1. **SUM:** Adds up a range of numbers. Example: `=SUM(A1:A5)`

2. **AVERAGE:** Calculates the average of a range of numbers. Example: `=AVERAGE(B1:B10)`

3. **MAX:** Returns the highest value in a range. Example: `=MAX(C1:C8)`

4. **MIN:** Returns the lowest value in a range. Example: `=MIN(D1:D7)`

5. **COUNT:** Counts the number of cells that contain numbers. Example: `=COUNT(E1:E6)`

6. **IF:** Performs conditional calculations. Example: `=IF(A1>10, "Yes", "No")`

7. **VLOOKUP:** Searches for a value in a table and returns a related value. Example: `=VLOOKUP(F1, A1:B10, 2, FALSE)`

8. **HLOOKUP:** Similar to VLOOKUP but searches in rows instead of columns.

9. **SUMIF:** Adds up values based on a specified condition. Example: `=SUMIF(G1:G5, ">50")`

10. **AVERAGEIF:** Calculates the average based on a condition. Example: `=AVERAGEIF(H1:H8, "<25")`

11. **COUNTIF:** Counts cells based on a condition. Example: `=COUNTIF(I1:I6, "Apple")`

12. **SUMIFS:** Adds up values with multiple conditions. Example: `=SUMIFS(J1:J10, K1:K10, "Red", L1:L10, "Large")`

13. **CONCATENATE:** Combines text from multiple cells. Example: `=CONCATENATE(A1, " ", B1)`

14. **LEFT:** Extracts a specified number of characters from the beginning of a cell. Example: `=LEFT(M1, 3)`

15. **RIGHT:** Extracts a specified number of characters from the end of a cell. Example: `=RIGHT(N1, 2)`

16. **LEN:** Calculates the length (number of characters) in a cell. Example: `=LEN(O1)`

17. **TRIM:** Removes extra spaces from text. Example: `=TRIM(P1)`

18. **DATE:** Creates a date value. Example: `=DATE(2023, 10, 12)`

19. **NOW:** Returns the current date and time.

20. **RAND:** Generates a random number between 0 and 1.

21. **ROUND:** Rounds a number to a specified number of decimal places. Example: `=ROUND(Q1, 2)`

22. **PI:** Returns the mathematical constant Pi (3.14159265358979).

23. **POWER:** Raises a number to a specified power. Example: `=POWER(2, 3)` (2^3)

24. **SQRT:** Calculates the square root of a number. Example: `=SQRT(16)`

25. **IFERROR:** Handles errors and returns an alternative value. Example: `=IFERROR(R1/S1, "Error")`

These are just a few examples of Excel formulas and functions. Excel provides a wide array of functions to perform various tasks, making it a powerful tool for data analysis and calculations.
