You will be surprised at how powerful Excel can get when fed with the right formulas. Excel formulas are very useful in handling large data sets efficiently. The good thing is that these formulas are very easy to learn. To understand this better, it is good to practice on excel formula with example.

Top Excel Functions with Formula examples (Tutorial 1: COUNTIF & IFERROR)


The COUNTIF function is used to show how many times a certain value appears. The formula is written as;

How to:

=COUNTIF (range, criteria)

If for example, you have a list of 50 names and would like to see how many times the name John appears in column A, the formula would be;

=COUNTIF (A2: A50, “John”)

excel formula with example

If this formula were to be used for other columns, it would have to be manually changed every time for a new column. To avoid this, absolute references are made. This would be written as;

=COUNTIF ($A$2:$A$50, “$D11”) where D11 is the new cell it has been copied into.

What is IFERROR function

Though this function is not a common appearance in the list of Excel formulas, it is very useful in handling errors.  This function is used to avoid error messages. When Excel encounters an error, it will often show up as #VALUE!.  Other error messages that come up include are #DIV.  The IFERROR function is written as;

How to:

=IFERROR (condition/value, what result if condition/value is wrong).

If for example there is a division formula in C2 that is A2/B2, the IFERROR formula would be written as; =IFERROR (A2/b2, “Review”) to avoid an error message. The word ‘Review’ would show up when Excel encounters a difficulty in executing the division formula if for example there is a text value that cannot be divided.

Screenshot example and scenarios (to make it more simple to understand):

excel formula with example

Scenario 1. Direct division formula without IFERROR function

600/30 = 20 {Formula in C2 =A2/B2}

Scenario 2. Direct division formula without IFERROR function where value contains a text

600a/30 = #VALUE! {Formula in C3 =A3/B3}

Scenario 3. Division formula with IFERROR function

600/30 =20 {Formula in D2 =IFERROR (A2/B2,”Review”)}

Scenario 4. Division formula with IFERROR function where value contains a text.

600a/30 =Review {Formula in D3 =IFERROR (A2/B2,”Review”)}
