What is IFERROR function in Excel?
The IFERROR function is one of the Logical functions of Excel.
It returns value_if_error if the expression is an error and the value of the expression itself otherwise.
We can find this in the Logical functions of the insert the function Tab.

Excel’s IFERROR Function: A Comprehensive Guide
The IFERROR function in Excel is a powerful tool for managing errors and preventing them from disrupting your calculations. It allows you to specify what should happen if a formula returns an error, such as #N/A, #VALUE!, #REF!, #DIV/0!, #NUM!, or #NAME?. Instead of showing the error message, you can display a custom message or a blank cell, or perform some other action.
Using the IFERROR Function in Excel for Error Management
One of the primary uses of the IFERROR function is to manage errors in your calculations. When a formula returns an error, it can cause your entire spreadsheet to become disrupted. By using the IFERROR function, you can prevent these errors from occurring and keep your spreadsheet running smoothly.
Example: Suppose you have a formula that calculates the average sales per day for a particular month, but there are no sales data available for some days. To avoid the #DIV/0! error, you can use the IFERROR function to display a custom message, such as “No Data Available”, instead of the error message.
=IFERROR(AVERAGE(B2:B31),”No Data Available”)
Mastering Excel’s IFERROR Function: Tips and Tricks
To get the most out of the IFERROR function, there are several tips and tricks that you should keep in mind. For example, you can use the nested IFERROR function to handle multiple types of errors at once, or you can use the IFNA function to handle specific errors like #N/A. Additionally, you can use the IFERROR function in conjunction with other Excel functions like VLOOKUP or SUMIF to create more complex formulas.
Example: If you have a table of student grades with some missing values, you can use the IFERROR function in conjunction with the VLOOKUP function to replace the missing values with a custom message.
=IFERROR(VLOOKUP(StudentName,GradeTable,2,FALSE),”Missing Grade”)
Common Applications of the IFERROR Function in Excel
There are several common applications of the IFERROR function in Excel. For example, you can use it to replace error messages with custom messages or to display a blank cell instead of an error message. You can also use it to correct errors in your data by performing calculations based on the type of error encountered. Finally, you can use it to streamline your formulas by reducing the number of error-checking functions you need to use.
Example: You have a list of product prices, and some of the prices have been entered as negative numbers due to a data entry error. To correct these errors, you can use the IFERROR function to subtract the negative price from a fixed amount, such as $100.
=IFERROR(IF(B2<0,100-B2,B2), “”)
To make the headings bigger, you can select the cells containing the headings, and then choose a larger font size from the Font section in the Home tab of the Excel ribbon. Alternatively, you can use the Format Cells dialog box to customize the font size, style, and other attributes of your headings.
Maximizing Productivity with Excel’s IFERROR Function
The IFERROR function in Excel is a versatile tool that can help you maximize productivity by streamlining your formulas and reducing the time it takes to troubleshoot errors. Here are some ways to use IFERROR to increase productivity:
1. Replace error messages with custom messages
Instead of showing an error message such as #N/A or #DIV/0!, you can use IFERROR to display a custom message of your choice. For example, suppose you have a formula that divides a sales figure by the number of units sold, but some cells contain zero values. You could use IFERROR to display “No Sales” instead of the #DIV/0! error message:
=IFERROR(Sales/Units,"No Sales")
2. Simplify nested functions
If you have several nested functions in a formula, it can be difficult to troubleshoot any errors that occur. By using IFERROR at the top level of the formula, you can simplify the structure and make it easier to read. Here’s an example:
=IFERROR(VLOOKUP(A1,Table,2,FALSE),0)
This formula looks up a value in a table and returns the corresponding value from the second column. If the lookup fails, IFERROR returns a value of 0 instead of an error.
3. Handle missing data
If your data contains missing values, you can use IFERROR to handle them gracefully. For example, suppose you have a list of product prices, but some of the prices are missing. You could use IFERROR to display a message indicating that the price is unknown:
=IFERROR(Price, "Unknown")
How to Use the IFERROR Function for Logical Tests in Excel
In addition to managing errors, you can use the IFERROR function in Excel to perform logical tests and make decisions based on the results. Here are some examples:
1. Check for a specific value
You can use IFERROR to check whether a cell contains a specific value. For example, suppose you have a list of product names and you want to flag any products that contain the word “organic”. You could use this formula:
=IFERROR(FIND("organic",A1),0)>0
This formula uses the FIND function to search for the word “organic” in cell A1. If it’s found, FIND returns the position of the first character of the word. IFERROR then converts any errors to zero values. The final comparison checks whether the result is greater than zero.
2. Check for multiple conditions
You can also use IFERROR to check for multiple conditions at once. For example, suppose you have a list of customer orders and you want to flag any orders that involve a product with a price over $100 or a quantity over 10. You could use this formula:
=IF(IFERROR(Price>100,FALSE),TRUE,IFERROR(Qty>10,FALSE))
This formula uses nested IF functions to check two different conditions. IFERROR is used to handle any errors that occur when comparing the price or quantity to the threshold values.
Excel’s IFERROR Function for Statistical Analysis
The IFERROR function in Excel can be useful for handling errors when performing statistical analysis. Here are some examples:
1. Calculate standard deviation
You can use the IFERROR function to calculate the standard deviation of a range of values, while ignoring any errors that might occur. For example, suppose you have a range of values in cells A1:A10, but some of the cells contain error messages. You could use this formula to calculate the standard deviation:
=IFERROR(STDEV(A1:A10),"")
This formula uses the STDEV function to calculate the standard deviation, but if there are any errors in the range, the IFERROR function returns a blank cell instead of the error message.
2. Perform regression analysis
You can also use the IFERROR function to perform regression analysis on a dataset, while handling any errors that might occur. For example, suppose you have two sets of data in columns A and B, and you want to perform linear regression analysis. You could use this formula:
=IFERROR(LINEST(B:B,A:A), "")
This formula uses the LINEST function to perform linear regression analysis on the data, but if there are any errors (e.g., if the ranges are not the same size), the IFERROR function returns a blank cell instead of the error message.
Common Errors When Using the IFERROR Function in Excel
While the IFERROR function can be very useful, it is important to avoid common errors when using it. Here are some mistakes to watch out for:
1. Overuse of IFERROR
One common mistake is to use IFERROR too often, which can make it difficult to troubleshoot errors in your formulas. It’s best to use IFERROR only where necessary, and to include more specific error-handling functions (such as ISNA, ISERROR, or IFNA) if you need to handle specific types of errors.
2. Incorrect syntax
Another error that can occur is incorrect syntax when using the IFERROR function. The correct syntax is:
=IFERROR(value, value_if_error)
where “value” is the cell or formula to be evaluated, and “value_if_error” is the value to be returned if an error occurs. Make sure that you include both arguments in the formula, and that they are separated by a comma.
Mastering the IFERROR Function in Excel for Business Professionals
The IFERROR function in Excel is a valuable tool for business professionals who want to manage errors and streamline their formulas. Here are some ways to use IFERROR in business applications:
1. Financial forecasting
You can use the IFERROR function to manage errors when creating financial forecasts. For example, suppose you have a series of forecasted sales figures in cells B2:B13, but the actual sales figures are not available for some months. You could use this formula to calculate the percentage difference between the forecasted and actual sales:
=IFERROR((B2-A2)/A2,"")
This formula uses the IFERROR function to handle any errors that occur when calculating the percentage difference. If there is no data available for a particular month, the IFERROR function returns a blank cell instead of the error message.
2. Project management
You can also use the IFERROR function to manage errors when working with project management data. For example, suppose you have a list of tasks in a project, and each task has a start date and an end date. You could use this formula to calculate the duration of each task:
=IFERROR(DATEDIF(A2,B2,"d"),"")
This formula uses the DATEDIF function to calculate the number of days between the start and end dates. If there are any errors (e.g., if the date values are not entered correctly), the IFERROR function returns a blank cell instead of the error message.
Excel’s IFERROR Function for Project Management
The IFERROR function can be very useful when working with project management data in Excel. Here are some examples of how to use it:
1. Calculate task duration
You can use the IFERROR function to calculate the duration of tasks in a project, while handling any errors that may occur. For example, suppose you have a list of tasks in a project, with their start dates and end dates. You could use this formula to calculate the duration of each task:
=IFERROR(DATEDIF(A2,B2,"d"), "")
This formula uses the DATEDIF function to calculate the number of days between the start date (in cell A2) and the end date (in cell B2). If there are any errors (such as missing or incorrect date values), the IFERROR function returns a blank cell instead of the error message.
2. Identify critical path tasks
You can also use the IFERROR function to identify critical path tasks in a project, while ignoring any errors that might occur. For example, suppose you have a list of tasks in a project, with their start dates, durations, and dependencies. You could use this formula to identify the critical path tasks:
=IFERROR(IF(MAX(IF(ISBLANK(C2:C10),0,D2:D10+C2:C10))=D2+MAX(IF(ISBLANK(C2:C10),0,D2:D10+C2:C10)),"Critical Path",""), "")
This formula uses an array formula to find the longest path through the project (i.e., the critical path). If there are any errors (such as missing or incorrect dependency values), the IFERROR function returns a blank cell instead of the error message.
3. Summarize project costs
You can also use the IFERROR function to summarize project costs, while handling any errors that may occur. For example, suppose you have a list of tasks in a project, with their durations and hourly rates. You could use this formula to calculate the total cost of each task:
=IFERROR(DAYS360(A2,B2)*C2*24, "")
This formula uses the DAYS360 function to calculate the number of days between the start date (in cell A2) and end date (in cell B2), and then multiplies that value by the hourly rate (in cell C2) and 24 (to convert hours to days). If there are any errors (such as missing or incorrect values), the IFERROR function returns a blank cell instead of the error message.
By using the IFERROR function in these ways, you can simplify your formulas, prevent errors from disrupting your calculations, and increase your productivity when working with project management data in Excel.
