How To Use ISERROR() Function in Google Sheets


Checks whether a value is an error.

Common questions about the ISERROR formula in Google Sheets:
  1. What is the purpose of the ISERROR formula?
  2. How does the ISERROR formula work?
  3. What is the syntax of the ISERROR formula?
  4. What types of errors can the ISERROR formula detect?
  5. Can the ISERROR formula be used with different data types?
  6. Are there any limitations or constraints when using the ISERROR formula?

Appropriate use of the ISERROR formula:
  1. Checking if a cell contains an error value: The ISERROR formula can be used to determine if a cell contains any type of error, such as #DIV/0!, #VALUE!, #REF!, #NAME?, #NUM!, #N/A, or #ERROR!
  2. Conditional formatting: The ISERROR formula can be applied to conditional formatting rules to highlight or format cells that contain errors.
  3. Error handling: The ISERROR formula can be used within other formulas or functions to handle errors and return alternative results or error messages.

Common mistyping of the ISERROR formula:
  1. Misspelling the formula name as "ISEROR" or "ISREROR."
  2. Incorrect capitalization, such as "iserror" or "IsError."
  3. Incorrect placement of parentheses or using the wrong syntax.

Inappropriate use of the ISERROR formula:
  1. Using the ISERROR formula without considering specific error types: It's important to specify the type of error you want to check for using other error-specific functions like ISNA().
  2. Using the ISERROR formula to ignore all errors: Blindly using the ISERROR formula to suppress all errors without proper error handling can lead to incorrect or misleading results.

Common pitfalls when using the ISERROR formula:
  1. Neglecting to handle the error case: Merely identifying the presence of an error without taking appropriate action or providing an alternative solution may result in incorrect data analysis or faulty calculations.
  2. Incorrectly assuming all errors have the same significance: Different errors may require different handling approaches, so it's important to understand the specific error and its impact on the calculation or analysis.

Common mistakes when using the ISERROR formula:
  1. Forgetting to wrap the ISERROR formula around the cell reference: The ISERROR formula should be used as ISERROR(cell_reference) to check if the referenced cell contains an error.
  2. Misinterpreting the output of the ISERROR formula: The ISERROR formula returns a Boolean value (TRUE or FALSE) indicating whether the referenced cell contains an error. It does not return the type of error.

Common misconceptions about the ISERROR formula:
ISERROR can fix errors: The ISERROR formula is used to detect errors, not fix them. It helps identify the presence of errors so that appropriate actions can be taken.
  1. ISERROR catches all types of errors: While the ISERROR formula can detect many common types of errors, it may not capture all possible errors. Using error-specific functions can help identify and handle different error types more accurately.
