Excel is a powerful tool widely used for data analysis, financial modeling, and much more. Understanding common Excel formulas is essential for efficiently managing and analyzing data. Here’s a guide to some of the most frequently used Excel formulas:
Basic Formulas
SUM
Purpose: Adds up all the numbers in a range of cells.
Example: =SUM(A1:A10) adds all numbers from cell A1 to A10.
AVERAGE
Purpose: Calculates the average of numbers in a specified range.
Example: =AVERAGE(B1:B10) finds the average of the numbers in cells B1 to B10.
MIN and MAX
Purpose: Returns the smallest and largest number in a set of values.
Example:
=MIN(C1:C10) finds the smallest number in the range C1 to C10.
=MAX(C1:C10) finds the largest number in the range C1 to C10.
COUNT
Purpose: Counts the number of cells that contain numbers.
Example: =COUNT(D1:D10) counts the number of cells with numeric entries in the range D1 to D10.
Text Functions
CONCATENATE
Purpose: Joins several text strings into one string.
Example: =CONCATENATE(E1, " ", F1) combines the text in cells E1 and F1 with a space in between.
LEFT, RIGHT, and MID
Purpose: Extracts a substring from a text string.
Example:
=LEFT(G1, 3) returns the first three characters from the string in G1.
=RIGHT(G1, 3) returns the last three characters from the string in G1.
=MID(G1, 2, 4) returns four characters starting from the second character of the string in G1.
LEN
Purpose: Returns the number of characters in a text string.
Example: =LEN(H1) gives the length of the string in cell H1.
Logical Functions
IF
Purpose: Performs a logical test and returns one value for a TRUE result, and another for a FALSE result.
Example: =IF(I1 > 100, "Above 100", "100 or below") checks if the value in I1 is greater than 100.
AND, OR
Purpose: Used to test multiple conditions.
Example:
=AND(J1 > 100, K1 < 200) returns TRUE if both conditions are met.
=OR(J1 > 100, K1 < 200) returns TRUE if at least one condition is met.
Lookup Functions
VLOOKUP
Purpose: Searches for a value in the first column of a table and returns a value in the same row from a specified column.
Example: =VLOOKUP(L1, M1:N10, 2, FALSE) looks for the value in L1 within the range M1:N10 and returns the corresponding value from the second column.
HLOOKUP
Purpose: Similar to VLOOKUP, but searches in the first row and returns a value from a specified row.
Example: =HLOOKUP(O1, P1:Q10, 3, FALSE) searches for the value in O1 within the range P1:Q10 and returns the corresponding value from the third row.
These formulas form the backbone of Excel functionality and serve as a foundation for more advanced operations and analysis. By mastering these, you can greatly enhance your productivity and capability in Excel.
