Formula generator for IFERROR function

The IFERROR function checks if the first argument is an error value. If it is not an error, it returns the first argument. If the first argument is an error, it checks if the second argument is present. If the second argument is present, it returns the second argument. If the second argument is absent, it returns a blank value.

How to generate an IFERROR formula using AI.

To obtain information on the ARRAY_CONSTRAIN formula, you could ask the AI chatbot the following question: “To get the IFERROR formula, you might ask the AI chatbot something like: "What is a formula in Excel that can handle errors and display a custom message instead?"

IFERROR formula syntax

The IFERROR function in Excel is used to handle errors in formulas. It checks if a formula results in an error and allows you to specify an alternative value or action if an error occurs. The syntax for IFERROR is: =IFERROR(value, value_if_error) - "value" is the formula or expression that you want to evaluate. - "value_if_error" is the value or action you want to take if the formula results in an error. If the formula in the "value" argument returns an error, the IFERROR function will return the value specified in the "value_if_error" argument. If the formula does not result in an error, the IFERROR function will return the result of the formula. For example, if you have a division formula that could result in a #DIV/0! error, you can use IFERROR to display a custom message instead of the error: =IFERROR(A1/B1, "Cannot divide by zero") This formula will calculate A1/B1, and if it results in an error, it will display the message "Cannot divide by zero" instead of the error. IFERROR is a useful function for handling errors in formulas and providing more user-friendly outputs.

Use Cases & Examples

In these use cases, we use the IFERROR formula to handle errors in Excel. It allows us to specify a value or an action to be taken if a formula results in an error. This is particularly useful when working with calculations that may encounter errors, such as dividing by zero or referencing invalid data. By using the IFERROR formula, we can gracefully handle these errors and display alternative results or messages.

Calculating Profit Margin


Calculates the profit margin by dividing the profit by the revenue. If there is an error in the profit calculation, it returns a blank.


=IFERROR(profit/revenue, "")

Determining Pass/Fail Status


Checks if a student's score is above the passing threshold. If the score is not available or there is an error, it returns a blank.


=IFERROR(IF(score>=passing_threshold, "Pass", "Fail"), "")

Calculating Loan Repayment


Calculates the monthly loan repayment amount based on the loan amount, interest rate, and loan term. If any of the input values are missing or there is an error, it returns a blank.


=IFERROR(PMT(interest_rate/12, loan_term*12, -loan_amount), "")

Frequently Asked Questions

  • The IFERROR function is used to handle errors in Excel formulas. It allows you to specify a value or action to be taken if an error occurs in the formula.
  • To use the IFERROR function, you need to provide two arguments: the first argument is the formula you want to evaluate, and the second argument is the value or action to be taken if an error occurs.
  • The IFERROR function can handle various types of errors, including #DIV/0!, #N/A, #NAME?, #NULL!, #NUM!, #REF!, and #VALUE! errors.
  • Yes, you can nest the IFERROR function within another function to handle errors within that function. This can be useful when you want to display a specific value or perform a specific action if an error occurs.
  • One important consideration when using the IFERROR function is that it only handles errors within the specific formula it is applied to. If you have multiple formulas in a cell or a range of cells, you need to apply the IFERROR function to each individual formula.
