Standard Error Types in Excel

In this article you will learn more about the various types of Error messages in Excel and what are the possible reasons for these types of errors.

What are the various types of Errors seen in Excel?

In Excel, there are several types of errors that can occur when working with formulas or functions. These error types indicate specific issues with the data or calculations performed. Here are the most common error types in Excel:

#DIV/0! 

This error occurs when a formula attempts to divide a number by zero. It indicates that the division operation is not possible and results in an undefined value.

#N/A 

This error stands for "Not Available" or "Not Applicable." It occurs when a value or data cannot be found within a lookup operation, such as using the VLOOKUP or HLOOKUP functions.

#NAME?

This error occurs when Excel does not recognize a text or cell reference in a formula. It usually happens when there is a misspelling or incorrect naming of a function, range, or named range.

#NULL!

This error occurs when a formula references an intersection of two ranges that do not intersect. It happens when using the space operator (a space between two references) instead of the intersection operator (a comma or space followed by a comma) in a formula.

#REF!

This error occurs when a cell reference in a formula is no longer valid or refers to a deleted cell, row, or column. It can happen when cells are deleted, inserted, or moved after a formula is entered.

#VALUE!

This error occurs when the wrong data type is used in a formula or function. It can happen when performing calculations on incompatible data types, such as trying to multiply text values.

#CIRCULAR_REFERENCE 

This error occurs when a formula refers to itself directly or indirectly, creating an infinite loop. Excel detects this circular reference and prevents the calculation from completing.

‍

These error types help identify specific issues in formulas or functions, allowing you to troubleshoot and correct them. By understanding these error messages, you can effectively identify and resolve formula-related issues in Excel.

What are some common error handling techniques in Excel?

In Excel, there are several ways to handle errors and prevent them from affecting the functionality and accuracy of your spreadsheets. Here are some common error handling techniques in Excel:

1. IFERROR Function: The IFERROR function allows you to handle specific errors by providing a fallback value or alternative calculation. It checks if an error occurs and returns a specified value if true, or the result of the formula if false. For example: =IFERROR(formula, "Error Message") or =IFERROR(formula, alternative calculation). This helps display custom messages or alternative values when an error occurs.
2. ISERROR/ISNA Function: The ISERROR function is used to check if a cell contains any error value. It returns "TRUE" if there is an error and "FALSE" if not. You can use this function with other functions or formulas to conditionally handle errors. For example: =IF(ISERROR(formula), "Error Message", formula). The ISNA function specifically checks for the #N/A error. It returns "TRUE" if the error is #N/A and "FALSE" otherwise. Similar to ISERROR, you can combine this function with others for error handling. 
3. Error Checking Options: Excel has built-in error checking options that can help identify and correct errors in formulas. These options can be accessed through the "Formulas" tab and include features such as error checking rules, error checking alerts, and error checking formulas. They provide visual indicators and suggestions to help you troubleshoot and fix formula errors.
4. Error Correction: When an error occurs in a formula, Excel provides an error indicator in the cell. Clicking on the error indicator displays a dropdown menu with options to help correct the error. You can choose to ignore the error, trace the error, evaluate the formula, or access additional help for error resolution.
