About ISERROR 🔗
Use the ISERROR function to determine if a specific cell in your Excel spreadsheet contains an error. It helps with error handling and data validation by evaluating error values in a cell. This function is useful for identifying errors in large datasets or complex calculations, enabling you to address them and maintain data accuracy.
Examples 🔗
If you have a formula in cell A1 that calculates the ratio of two numbers, and you want to check for errors like divide by zero, use the formula =ISERROR(A1). This will return TRUE if A1 has an error, such as #DIV/0!, and FALSE otherwise.
When working with a dataset where some cells might have error values due to incorrect inputs or formula errors, you can combine ISERROR with conditional formatting to highlight these cells for further review and correction.
Notes 🔗
The ISERROR function checks for error values such as #N/A, #VALUE!, #REF!, #DIV/0!, #NUM!, #NAME?, and #NULL!. Use it to identify errors in your data sets and formulas. This allows you to take corrective actions to maintain the accuracy of your calculations.
Questions 🔗
