Pseudo Code for Excel Functions and Formulas

This document outlines the essential pseudo code for various commonly used functions and formulas in Excel. The focus is on key functionalities and their logical flow.

1. SUM Function

Purpose

Calculate the sum of a range of numbers.

Pseudo Code

FUNCTION SUM(range)
    total = 0
    FOR each cell in range
        total = total + cell.value
    END FOR
    RETURN total
END FUNCTION

2. AVERAGE Function

Purpose

Compute the average of a set of values.

Pseudo Code

FUNCTION AVERAGE(range)
    total = SUM(range)
    count = COUNT(range)
    IF count > 0 THEN
        RETURN total / count
    ELSE
        RETURN 0
    END IF
END FUNCTION

3. IF Function

Purpose

Return one value if a condition is true and another value if it is false.

Pseudo Code

FUNCTION IF(condition, trueValue, falseValue)
    IF condition THEN
        RETURN trueValue
    ELSE
        RETURN falseValue
    END IF
END FUNCTION

4. COUNT Function

Purpose

Count the number of cells that contain numbers in a range.

Pseudo Code

FUNCTION COUNT(range)
    count = 0
    FOR each cell in range
        IF cell.value IS NUMERIC THEN
            count = count + 1
        END IF
    END FOR
    RETURN count
END FUNCTION

5. VLOOKUP Function

Purpose

Search for a value in the first column of a table and return a value in the same row from a specified column.

Pseudo Code

FUNCTION VLOOKUP(lookupValue, tableArray, colIndex, exactMatch)
    FOR each row in tableArray
        IF row[0] = lookupValue THEN
            RETURN row[colIndex]
        END IF
    END FOR
    IF exactMatch THEN
        RETURN "Value not found"
    END IF
END FUNCTION

6. CONCATENATE Function

Purpose

Combine multiple strings into one string.

Pseudo Code

FUNCTION CONCATENATE(strings)
    result = ""
    FOR each string in strings
        result = result + string
    END FOR
    RETURN result
END FUNCTION

7. MAX Function

Purpose

Return the largest value from a set of numbers.

Pseudo Code

FUNCTION MAX(range)
    maxValue = range[0]
    FOR each cell in range
        IF cell.value > maxValue THEN
            maxValue = cell.value
        END IF
    END FOR
    RETURN maxValue
END FUNCTION

8. MIN Function

Purpose

Return the smallest value from a set of numbers.

Pseudo Code

FUNCTION MIN(range)
    minValue = range[0]
    FOR each cell in range
        IF cell.value < minValue THEN
            minValue = cell.value
        END IF
    END FOR
    RETURN minValue
END FUNCTION
