The ISERR function in Google Sheets is a powerful tool used to evaluate whether a given value is an error, excluding the `N/A` error. This function is pivotal in data analysis as it allows users to filter out errors that may skew their calculations or overall data interpretation.

Syntax

ISERR(value)

• value: The input value you want to test for an error.

Example #1

ISERR(DIV/0!)

This checks if the division by zero error is present, returning TRUE since it is an error. Example result: TRUE.

Example #2

ISERR(N/A)

This evaluates whether the error is anything other than `N/A`. The result will be FALSE as the function specifically ignores `N/A`. Example result: FALSE.

Example #3

ISERR(10)

This checks a standard number to see if it contains an error. In this case, the result is FALSE, indicating no error. Example result: FALSE.

Error handling

If an error occurs while using the ISERR function, consider the following:

• VALUE!: Indicates that the input is of an unexpected type, such as text instead of a number.
• REF!: Occurs when the function references a cell that is not valid, like a deleted cell.
• NUM!: This error appears when a function receives an inappropriate argument, such as attempting a complex calculation that cannot be performed.

Conclusion

In summary, the ISERR function is an essential tool for identifying error values in Google Sheets, except for `N/A`. Its ability to help discern between valid responses and errors enhances data integrity and offers a clearer view of the data landscape. By carefully analyzing error types, users can develop more robust data sets, making data-driven decisions more effectively.
