Excel ISERROR Function: A Guide to Mastering Error Detection

Excel ISERROR Function

Excel-ISERROR-Function

When to Use the Excel ISERROR Function in Excel

The ISERROR function check whether a formula or expression results in an error. It is particularly useful for error handling and ensuring the accuracy of your data.

What Excel ISERROR Function Returns

The Excel ISERROR function returns a logical value – TRUE if the specified expression or formula results in an error, and FALSE if there is no error. This can be extremely valuable in creating conditional formulas or in troubleshooting errors within your data.

Syntax of Excel ISERROR Function

The syntax of the Excel ISERROR function is as follows:

=ISERROR(value)

Input Arguments

Here is the input argument for the Excel ISERROR function:

value: The expression or formula you want to check for errors. It can be a cell reference, a formula, or a numeric value.

Examples of the Excel ISERROR Function

Here are few examples demonstrating the usage of the ISERROR function in Excel:

Example 1: Basic Usage

To make a simple ISERROR formula, provide a reference to the cell you wish to examine for errors. If an error is present, the result will be TRUE; if the tested cell is error-free, the outcome will be FALSE:

Excel-ISERROR-Function-Example-1

Example 2: Combining with IF Function

You can use the Excel ISERROR function in conjunction with the IF function to display a custom message when an error is detected. For example: =IF(ISERROR(A1), “Error in cell”, “No error”)

Excel ISERROR Function Example 2

Example 3: Combining with IF Function & VLOOKUP Function

Suppose you have all student names in column A, and column D contains the list of students who have obtained passing marks in a recent test, as shown in the image below:

Excel ISERROR Function Example 3

You want to figure out which students in the whole class passed the test. To automate this process, you decide to use the formula =IF(ISERROR(VLOOKUP(A2,D2:E8,2,FALSE)),”No”,”Yes”) in cell B2.

Excel-ISERROR-Function-Example-4

Let’s break down the formula:

  • VLOOKUP(A2,D2:E8,2,FALSE): This part of the formula uses the VLOOKUP function to search for the value in cell A2 within the range D2:E8. It looks in the second column of this range (column E) and retrieves the corresponding value. If the student’s name is found, it returns the marks obtained; otherwise, it returns an error.
  • ISERROR(VLOOKUP(A2,D2:E8,2,FALSE)): The ISERROR function checks if there is an error in the result of the VLOOKUP function. If there is an error (meaning the student’s name is not found in the list), ISERROR returns TRUE; otherwise, it returns FALSE.
  • IF(ISERROR(VLOOKUP(A2,D2:E8,2,FALSE)),”No”,”Yes”): The IF function then evaluates the result of the ISERROR function. If ISERROR returns TRUE (indicating an error, meaning the student’s name is not found), the formula returns “No”. If ISERROR returns FALSE (indicating no error, meaning the student’s name is found), the formula returns “Yes”.

In simpler terms, the formula checks if the student’s name in cell A2 is present in the list of qualified students. If the name is found, it returns “Yes”; otherwise, it returns “No”.

Difference between ISERROR and IFERROR in Excel

Both ISERROR and IFERROR are functions in Excel that help deal with error. Here is what sets them apart:

  • ISERROR checks if a value is an error or not.
  • IFERROR, however, is designed to hide errors. When there is an error, it gives you a different value that you choose.

At first, IFERROR might seem like a quicker way to do what IF ISERROR does. But if you look closely, there is a key difference:

  • IFERROR only lets you pick a value if there is an error. If there is no error, it just shows the result of the tested value or formula.
  • On the other hand, ISERROR is more flexible. It lets you handle both situations – what to do if there is an error and what to do if there is no error.

To verify whether a cell is not blank, incorporate the ISBLANK function within the NOT function, as illustrated below:

Excel-ISBLANK-Function-Example-3

The formula =NOT(ISBLANK(A1)) checks if cell A1 is not empty. It returns TRUE if A1 has data and FALSE if A1 is empty.

The NOT function in Excel is used to reverse or negate logical values. It is handy for flipping TRUE to FALSE and vice versa. This function is commonly employed in logical tests, especially when checking for conditions like non-empty cells or the absence of certain criteria.

Sometimes, instead of using the ISBLANK function, formulas use a simpler method. This involves using an empty set of quotation marks (“”) along with Excel’s equal (=) or not equal (<>) operators.

For example, to see if A1 is empty, you can use:

Excel-AVERAGEIFS-Function-Example-4

In the above example, you can observe that checking for empty cells can be accomplished using either =ISBLANK(A1) (refer to Example 1) or =A1=””, both yielding the same result.

Similarly, evaluating non-empty cells can be done with either =NOT(ISBLANK(A1)) (refer to Example 2) or =A1<>0, with both approaches producing identical outcomes.

Example 3: Applying Conditional Formatting

Imagine you have the following dataset, and you want to highlight the cells that are empty.

Excel-ISBLANK-Function-Example-4

Now, let’s see how we can highlight empty cells using conditional formatting and the ISBLANK function.

1. Select the cell range; in our case, it is B2:E13.

2. Choose the Home tab, then go to Conditional Formatting, and select New Rule.

Excel ISBLANK Function Example 5

3. Now, the New Formatting Rule dialog box will open. Under ‘Select a Rule Type’, choose ‘Use a formula to determine which cells to format’.

4. Next, in ‘Edit the Rule Description’, input the formula =ISBLANK(B2).

5. Now, click on the ‘Format’ tab.

Excel ISBLANK Function Example 6

6. Now, in the Format Cells dialog box, select the Fill tab.

7. Choose your preferred color.

8. Click on OK, then OK again.

Excel AVERAGE Function: Elevate Your Data Analysis Game

Excel AVERAGE Function

Excel-AVERAGE-Function

When to Use the Excel AVERAGE Function in Excel

The AVERAGE function in Excel is a powerful tool used for calculating the arithmetic mean of a range of numbers. It is particularly handy when you need to analyze data sets, assess trends, or make informed decisions based on numerical values.

What Excel AVERAGE Function Returns

The Excel AVERAGE function returns the average (mean) of a given set of numbers. This can be extremely useful in scenarios where you want to understand the central tendency or typical value of a dataset.

Syntax of Excel AVERAGE Function

The syntax of the Excel AVERAGE function is as follows:

=AVERAGE(number1, [number2], …)

Input Arguments

Here are the input arguments for the Excel AVERAGE function:

number1, [number2], …: These are the numerical values, cell references, or ranges that you want to include in the average calculation. You can input up to 255 arguments.

Examples of the Excel AVERAGE Function

Here are few examples demonstrating the usage of the AVERAGE function in Excel:

Example 1: Basic Usage

One common method of utilizing the AVERAGE function involves specifying a range, as demonstrated below. The formula in cell E2, when copied downward, is:

Excel-AVERAGE-Function-Example-1-1

Each time a new row is added, the AVERAGE function figures out the average of the scores for each person.

Example 2: An Empty Cell & Cell with a zero value.

The AVERAGE function automatically ignores empty cells. In the example below, observe that cell B3 is empty, and AVERAGE simply excludes it, calculating the average using only the values in A3 and C3.

Additionally, if a cell contains zero, like in cell B4, the Excel AVERAGE function considers it in the calculation, including it as part of the average value.

Excel-AVERAGE-Function-Example-2

Note: Cells with text, logical values (TRUE and FALSE), or error values are also ignored.

Example 3: Finding the Average of the TOP 3

Imagine you are a teacher with students’ quiz scores in Excel. You want to know the average of the top three scores. Using Excel, you can figure out the average of the highest three values by using both the AVERAGE and LARGE functions with the formula:

Excel AVERAGE Function Example 4

Breaking down the formula: =AVERAGE(LARGE(B2:B11,{1,2,3}))

  • LARGE(B2:B11,{1,2,3}): The LARGE function is used to retrieve the n-th largest value in a data set. In this case, it is retrieving the 1st, 2nd, and 3rd largest values from the range B2:B11. So, it returns an array of three values: {96,93,87}
  • AVERAGE(LARGE(B2:B11,{1,2,3})): This takes the average of the three values obtained from the LARGE function. So, it adds up these three values and divides by 3 to get the average.

So, the result of the formula is 92, which is the average of the three largest scores in our data set.

Extra Notes

● You can use cell references, numerical values, or ranges as input arguments.

● AVERAGE counts zeros. Use AVERAGEIF or AVERAGEIFS to ignore zeros.

● To quickly find an average without using a formula, check the status bar. Just select the cells you want to average and check the status bar

Excel-AVERAGE-Function-Example-3

● If you put TRUE or FALSE in a formula, it counts as 1 or 0. For example, AVERAGE(TRUE, FALSE) gives 0.5, which is the average of 1 and 0.

● If you don’t have valid numbers in what you are calculating, you will get an error: #DIV/0!
