Microsoft Excel - Working with excel's conditional functions

1. Microsoft Excel – Working with Excel’s Conditional Functions

Conditional functions perform calculations or return values based on conditions.

Common conditional functions:

• IF()
• COUNTIF(), COUNTIFS()
• SUMIF(), SUMIFS()
• IFERROR()
• AND(), OR(), NOT()

These are widely used in reporting, validation, dashboards, and analysis.

2. Working with Excel Name Ranges

A Named Range assigns a meaningful name to a cell or range.

Example: 

Instead of using

=SUM(A1:A10)

Use:

=SUM(Sales)

How to create a Named Range:

• Select the cells
• Go to Formulas → Define Name
• Enter the name (no spaces)
• Click OK

3. Advantages and Disadvantages of Excel Name Ranges

✅ Advantages

Improves readability of formulas

Easier maintenance

Reduces formula errors

Useful in complex models

Works well with conditional functions

❌ Disadvantages

Difficult to manage in very large workbooks

Hidden names can cause confusion

Not always intuitive for beginners

Broken references if ranges are deleted incorrectly

4. Editing an Excel Name Range

To edit a Named Range:

Go to Formulas → Name Manager

Select the name

Click Edit

Change range or name

Click OK

5. Using Excel’s IF() Function

The IF function returns one value if a condition is TRUE, another if FALSE.

Syntax:

=IF(logical_test, value_if_true, value_if_false)

Example:

=IF(A1>=50,"Pass","Fail")

6. Excel’s IF() Function with a Name Range

Assume:

Named Range: Score → A1

=IF(Score>=60,"Qualified","Not Qualified")

This makes formulas easier to understand and reuse.

7. Nesting Functions with Excel

Nesting means using one function inside another.

Example:

=IF(A1>=50, IF(A1>=75,"Distinction","Pass"),"Fail")

8. Nesting Excel’s AND() Function within the IF() Function

Use AND() when multiple conditions must be TRUE.

Syntax:

=IF(AND(condition1, condition2), value_if_true, value_if_false)

Example:

=IF(AND(A1>=50, B1="Yes"), "Eligible", "Not Eligible")

9. Using Excel’s COUNTIF() Function

Counts cells that meet one condition.

Syntax:

=COUNTIF(range, criteria)

Example:

=COUNTIF(A1:A20, ">=60")

Counts students scoring 60 or above.

10. Using Excel’s SUMIF() Function

Adds values that meet a specific condition.

Syntax:

=SUMIF(range, criteria, [sum_range])

Example:

=SUMIF(A1:A10,"Electronics",B1:B10)

Sums sales where category is Electronics.

11. Using Excel’s IFERROR() Function

Handles errors gracefully.

Syntax:

=IFERROR(value, value_if_error)

Example:

=IFERROR(A1/B1, 0)

Prevents #DIV/0! errors.

🔑 Practical Business Use Case

=IFERROR(

   IF(AND(Sales>=Target, Region="East"),"Bonus","No Bonus"),

"No Data")
